The Complete Guide to FamilyTreeDNA

This is the book I wish I’d had nine years ago when dad and I tested with FamilyTreeDNA. It is now proving invaluable in helping me finally navigate our tests in an informed way. I’ve also been reminded about biobanking which means, even though dad died a few years ago, I can upgrade and expand his tests – and crucially know how to understand and make best use of the results.

Written by DNA expert Roberta Estes, who you may know as the author of the DNAeXplained blog, it is 247 pages packed with information to help you choose which FamilyTreeDNA test is right for you, and to ensure you get the most out of your test results. Those pages run to 11 chapters, walking you through the types of tests, who they are relevant for, along with their various associated tools.

Whenever I see a book review, I always want a run-through of the contents to see if what’s covered is of interest to me. After all, I need to make sure I’m spending my money wisely. So I’ve listed the chapters, and included the page numbers, to give an idea about what is covered, and the depth devoted to each broad topic.

  • Chapter 1: Types of Testing – Y-DNA, Mitochondrial DNA, Autosomal DNA, and X-DNA. Pages 6-10.
  • Chapter 2: Setting Yourself Up For Success. Set-up preparations to help get the most from your test. Pages 11-23.
  • Chapter 3: Y-DNA – Your Father’s Story. A detailed explanation of test options and goals, which shows how to use your results. Pages 24-96.
  • Chapter 4: Mitochondrial DNA – Your Mother’s Story. It explains the goals of this test, covers matches, what they mean and how to take those further. Pages 97-131.
  • Chapter 5: Autosomal DNA – The Family Finder Test. Probably the best-known test type, with matches to all family lines. Pages 132-172.
  • Chapter 6: X Chromosome – Described as your secret tool that’s included with Family Finder, it shows how this can be used. Pages 173-186.
  • Chapter 7: Ethnicity – My Origins. How this is calculated, the caveats around it, plus ethnicity chromosome painting. Pages 187-206.
  • Chapter 8: Advanced Matching. A useful, and often-overlooked, filtering tool. Pages 207-208.
  • Chapter 9: Finding, Joining and Utilizing Projects. An overview of various DNA projects, what to expect when joining one, and the benefits of getting involved. Pages 209-217.
  • Chapter 10: Third Party Tools. Covers Genetic Affairs and DNA Painter. Plus creating a powerful DNA Pedigree Chart to weave the various tools together. Pages 218-224.
  • Chapter 11: Creating Your Step-By-Step Roadmap. A useful bullet-point roadmap summary of all the various FamilyTreeDNA tests and third-party tools. Pages 225-230.
  • Glossary. This explains in straightforward terms the sometimes daunting vocabulary associated with DNA testing. Pages 231-247.

As you might have spotted from the above, there’s no index. This is a potential drawback, because it is less easy to home in on a specific issue. The chapters though are divided into bite-sized chunks, which are outlined in the chapter sub-headings and these sub-headings might, in some instances, act as a proxy index.

Throughout the book, there are plenty of graphics to help illustrate and explain, and there are also handy associated tip boxes.

Understanding DNA testing can be bewildering, and there is no doubt that this is a book which requires concentration. But it does help explain a complex subject, and makes it more accessible to those of us with less grounding in science.

The Complete Guide to FamilyTreeDNA is published by Genealogical Publishing Company, and is available in eBook, non-colour paperback and colour paperback formats – so there are a choice of reading options and price points.

Be aware, there are pros and cons with each.

I have the full colour paperback version of the book – something I welcome, given the number of charts and diagrams, the meaning of which might get lost in the black/white/grayscale paperback. But the colour paperback version does cost more, and price is an important consideration. Checking the Genealogical.com website, there is a free colour supplement download available for selected pages, so this could provide a workaround for the non-colour paperback. And the eBook is in full colour.

I personally prefer a physical book, as best suited to my reading and learning style. The drawback of the paperback format is the absence of footnote hyperlinks to take you directly to the DNAeXplained website references. I imagine you’d get that with the eBook version.

My edition was published in August 2024, ISBN 9780806321400. I’ve attached the Amazon link, and also the Genealogical.com link for all versions.

My conclusion. If you have invested in testing with FamilyTreeDNA, I’d say it is worth the extra outlay on this book, to make sure you’re getting the most from your results.

Full disclosure: I received a free copy of the colour printed paperback book from Genealogical.com in return for a honest review. I have expressed my truthful opinion in the above review.

Genetic Genealogy: it’s all in the Hill (DNA) – Part 3, No Silver Bullet

This is the third in my series of posts about my genetic genealogy journey. I ended my last post at the waiting game phase, all kits on their way. Things have progressed and I thought it helpful to provide an update.

I have included the information below of the various test stages to give some indication as to the variability of posting/processing times:

Test Type Posted Arrived Lab Processing Starts Anticipated Result Date Result Arrived
Ancestry autosomal (mum) 27 June 3 July 7 July 6-8 weeks 13 July
Ancestry autosomal (dad) 27 June 15 July 18 July 6-8 weeks
FTDNA Family Finder (me) 29 June 11 July including lab processing stage 5-19 August
FTDNA Y-DNA 37 (dad) 29 June 13 July including lab processing stage 23 Sept – 7 October
FTDNA mtFull Sequence 29 June 13 July including lab processing stage 26 August – 9 September

There is a lengthy delay in the anticipated result date of the FTDNA Y-DNA test. Hopefully this is a good sign, due to its popularity and hence the number of testers.

But the thing I found must perplexing was the difference in timescales for mum and dad’s Ancestry tests. These were both posted the same day from England to Dublin. The results for mum’s test came through significantly ahead of schedule, in fact even before dad’s vial of spit got there.

I really did suspect his was lost in the post but, when I asked, Ancestry said it allows 20 working days before a test is designated such.

More amazingly the FTDNA tests posted a couple of days after dad’s Ancestry one, and destined for Texas, arrived before his Ancestry test.

But dad’s test did finally reach its destination. So the moral of the story, which seems to be the DNA theme,  is do not give up hope and do not assume tests posted on the same day will arrive at roughly the same time! And one final thing to watch out for, there can be a delay between the test actions being annotated on the site and the email notification reaching you.

Mum’s Ancestry results came in on 13 July, a mere 17 days after posting. I have now had a quick preliminary look at them and these are my initial findings.

First thing to say is the site is easy to navigate and a pleasing mix of charts, tables and expandable “?” Boxes. It is all very intuitive and clear.

In terms of ethnicity there are no surprises. My mum has an English mother and Irish father. Her ethnicity results show 63% Great Britain, 34% Ireland. Of the four trace regions, Ancestry state “it is possible that these regions appear by chance and are not actually part of your genetic ethnicity”. So on this basis I am not claiming any tentative Armada, possibly false in any case, ancestry.

The results correspond with all my research to date (going back to the early 17th century on mum’s maternal line). It is good to have general confirmation of my research. But this is more an interesting coffee-table talking point rather than anything more substantive.

Then onto the meaty stuff – the DNA matches. The upfront view is mum has 44 4th cousins or closer and one shared ancestor hint. The latter is like the Ancestry tree shaky leaves.

I excitedly went to the “View all DNA matches” button and immediately felt overwhelmed, but thrilled, to see 57 pages of them, with around 50 entries per page. These are split into relationship ranges and confidence levels. The 4th cousin box refers to possible 4th – 6th cousins range and this is the first batch of matches listed in mum’s case, as this is the closest identified relationship.

Mum naturally has a significantly larger distant cousin category, with a possible range of 5th– 8th cousins. This is the remaining 56 and a bit pages.

Ancestry assign the following “confidence” ratings to the matches: “Extremely High”, “Very High”, “High”, “Good” and “Moderate”.

At this point it may be worth mentioning that ISOGG has a useful piece explaining the Ancestry confidence scores and their realism. It may be that the percentages for sharing a common ancestor are set too high[1]. There is also the caveat that the “AncestryDNA database is 99% American, and it is not yet known if these ranges will apply in the same way to other populations”.

Enthused I spent an afternoon ploughing through the first page of matches, only to become increasingly frustrated. This page included all 44 4th cousin matches. Six of these had “extremely high” confidence markings and the remainder “very high”. There were also two “very high” and four “high” distant cousins on this page.

Clicking onto the individual matches brings you to the next level. There is a “Pedigree and Surnames” tab which identifies all the surnames associated with the match’s tree. Helpfully shared surnames are pinpointed at the start, so this cuts out trawling through a whole list of surnames to pick out the ones in common. There is also the tree section on the right hand side of the page.

A second tab entitled “maps and locations” has a summary column as well as a map with coloured indicators identifying your family tree locations (blue) and those of the DNA match (mustard). Any shared locations are immediately recognisable, as the pointer for these is green.

A word of caution though – the maps are not entirely accurate. I uploaded my tree via a Family Historian GEDCOM file. The Ancestry programme has some fundamental discrepancies because my descriptors do not accord exactly with the Ancestry format. For example some of my Yorkshire ancestors are placed in the Isle of Man, Kent and the North East. I have corrected this.

Of less importance, but useful to know, is that if a vague location descriptor is attached, such as England or Ireland, the pointer will appear in the middle of the country. Or some may have assigned a county level rather than place-specific location. For example I have seen several matches with County Mayo as a location, (including a couple on my tree), but no further detail as to where in Mayo. So do not take the pointers at face value.

Worth using is the “Note” box. I am entering brief details about the DNA match’s tree and any obvious connections. It is also helping me keep track of the reviewed matches.

However my initial enthusiasm soon evaporated as it began to feel more like an exercise in futility. Of the 44 4th cousin matches six have private trees, although some of these do have public trees elsewhere on Ancestry; 11 have no tree; and five have less than ten people in their tree. Possibly some of these are individuals trying to find their DNA roots. Though this means straightaway a significant proportion are rendered relatively meaningless for my DNA purposes, at least for the immediate future.

When I first embarked on this journey I did wonder about linking my hitherto private tree to the test. I have for several years steered clear of putting my tree in the public domain, for privacy/copying reasons, having had my fingers burned years ago when I had a public Genes Reunited tree. It was a horrid experience and that copied information is still out there on a website.  It is not something I ever wish to repeat. So I get perfectly why some trees are private. Others may, for personal family sensitivities, decide against a public tree. It is after all an individual decision.

However in the end I decided to do a reduced, skeleton-form tree specifically for DNA test purposes. My reasoning for doing this is  having a private tree might cause people to by-pass me; it might be of assistance to other potential matches and facilitate contact in the interest of a shared goal; it could eliminate protracted fishing-questions; and it hopefully will  minimise the risk of wholesale copying, my big fear.

Anyway, back to the DNA results. Of the remainder of mum’s matches with trees of more than ten individuals, a couple are of peripheral interest and I may in due course make contact. At least though there is something concrete to base any contact with the tree-owners on. For the other matches on this first page there is no obvious connection.

I will go through the remaining 56 pages of matches over the coming months. But I will prioritise my search focusing first on those with larger, accessible trees.  I will also make more judicious use of the location/surname search filters as this will indicate common data  even in private trees, although in the latter cases just at the top level. And hopefully, as I become more familiar with what the site has to offer, my frustration will decrease.

And I have not entirely given up hope. My mum’s shared ancestor hint is a distant cousin match with a “good” confidence rating. This appears on page four of the matches. There is a tree attached. And, from this, the match is at 6th cousin level. It does not break down any brick walls for me, but it is a start.

So, in summary, I am finding that genetic genealogy is no silver bullet to break through brick walls. It is more of a long game and another tool in the genealogy box. Hopefully DNA match success rates for me will improve as more and more people, especially from England and Ireland[2], sign up. I am even considering doing the test myself.

But the bottom line is you are still reliant on people linking a meaningful tree to their DNA test; or those with private trees responding to messages; and those trees being accurate.
