Day Job - no time for one!

Night Job - genealogy. For more details of all my activities, see my website: http://pwaldron.info/

How did you get into genealogy?
I am a third generation genealogist. My grandfather began work on the family tree when he retired at 65 in 1949. His mother had four children before she turned 21, including my grandfather and his identical twin, and she lived to 88, so was still around to help him. The identical twins posed a further problem for those who like to calculate expected percentages of DNA shared - by marrying two sisters, whose own father had married twice, to two first cousins. My father caught the genealogy bug from his father and passed it on to me at a young age. At the age of 13, I rewrote the whole tree. I've now spent 30 years trying to get it all into a computer database. Every time I think I'm nearly finished, another batch of new records comes online.

Tell us about your involvement with genetic genealogy
My degrees in mathematical sciences, economics and finance included a lot of statistics, which inspired my curiosity about drawing genealogical inferences from genetic data. The jargon finally began to make sense when I first heard Maurice Gleeson speak at the Irish Genealogical Research Society in March 2013. A few months later, Katherine Borges swabbed me at Genetic Genealogy Ireland 2013 and I have been hooked since my results arrived a month or so after that. My closest match at the time was a lady who was adopted in 1938, but my best efforts to help her have so far turned up nobody closer to her than a few of her second cousins. Other adoption and fostering cases, including the one that inspired the title for my talk at GGI2016, have proved much easier to solve. I've also taken my own County Limerick ancestry back another two generations as the result of a DNA match between my first cousin and our fourth cousin twice removed, whom I already knew without ever suspecting a relationship or discussing our common roots.

I am now co-administrator with Terry Fitzgerald of the Clare Roots project at
https://www.familytreedna.com/groups/clare-roots-society/about
which was established to coincide with Maurice Gleeson's talk at the monthly Clare Roots Society meeting on 19 November 2015. By 3 October 2016, it had 358 members. Anyone with an ancestor who lived in County Clare is welcome to join. I have also set up a Clancy Surname Project and am working on establishing an Irish Waldron Surname Project.

I have recruited around 100 people to genetic genealogy in Clare, Limerick, Mayo and other ancestral heartlands via the DNA Outreach IRL project. Three years ago, the top 30 matches for any Irish person getting autosomal DNA results were typically complete strangers; nowadays, I expect to know personally about six of the top 30 matches of anyone from West Clare that I swab. Working out the relationships can still be a challenge.

What will you be talking about?

My presentation will combine examples of the successful application of autosomal DNA matching from my own experience with my thoughts on the statistical shortcomings of the current matching methodology. Examples will include how to use phasing and triangulation to confirm or refute suspected relationships, often revealing unexpected double relationships. I will demonstrate other tips and tricks for managing lists of DNA matches. I will show how DNA matching inter-relates with adoption and inheritance searches, marriage dispensations, bad record-keeping, and other aspects of genealogical research.

My examples will show how DNA matching unites the Irish diaspora around the world. Just like the financial markets, the work goes on around the clock, with Irish researchers often passing the baton at bedtime to those on the west coast of the USA, who pass it on to members of the diaspora in the Antipodes, who may have solved the problem by the time we wake up here in Ireland the next morning.
