Family Tree DNA’s November Conference - 4 days, 2 hrs ago

I managed to get registered today for The 13th Annual International Conference on Genetic Genealogy held each year by Family Tree DNA and I’ll be going to Houston from November 10 to 12 to attend. This is a tough one to get into (unless you are a speaker) as registration is only open to FTDNA group ...

GCGS 2017 Day 3 - Sun, 15 Oct 2017

#cangensummit2017 – The final day at the Great Canadian Genealogy Summit in Halifax, Nova Scotia was a half-day with 6 talks in 2 tracks. We all met for a breakfast together, and then I led off repeating my talk from the day before on intro DNA. I had a few less people than the day before since many had ...

Friday afternoon the started with Jan Raska from Pier 21, of the Canadian Museum of Immigration providing a very interesting keynote for the almost 60 attendees who arrived in time for his talk. ...

My DNA Football Team - Wed, 11 Oct 2017

I was thinking about my 1 year old grand-nephew this morning, and how he and I would look to be half-sharing about a quarter of our DNA in a chromosome browser. Well that would make my grand-nephew the quarterback of my DNA Football team. His father, my nephew, would be the halfback. My daughters would be ...

The Great Canadian Genealogy Summit - Mon, 9 Oct 2017

#cangensummit2017 - On Thursday, I’ll be flying 2,600 km (1,600 miles), but still be in Canada, as I travel to Halifax, Nova Scotia for the Great Canadian Genealogy Summit being held from October 13 to 15. I’ll be one of 12 speakers, all of us Canadian, giving 18 talks on various subjects of genealogical ...

Deep Ancestors - Mon, 2 Oct 2017

In the DMT documentation on the Interpreting Results page, I have a section called Deep Ancestors. It says: If the Triangulated Group is from a common ancestor, then there may be smaller identifiable groups within it that are either from a later crossover down one descendant line (in which case all the ...

Triangulation does NOT mean IBD - Mon, 25 Sep 2017

When I was first learning about autosomal DNA analysis, just over a year ago, I was under the misconception that if three people triangulate on a segment, then that segment is IBD (Identical by Descent). A segment that is IBD is one that is passed down from a common ancestor. These are the segments you are ...

The IAJGS Conference 2017 - Mon, 31 Jul 2017

I’ve returned from Orlando after the week-long #IAJGS2017 (International Association of Jewish Genealogical Societies) Conference on Jewish Genealogy. This was my 8th International genealogy conference, my first being RootsTech 2012, but it was my first IAJGS Conference. The venue was The Swan ...

DMT Version 1.5.1 and IAJGS and DMT Workshop - Tue, 18 Jul 2017

I fixed a few bugs in Double Match Triangulator that I found while preparing for my workshop at the IAJGS Conference on Monday. I also changed DMT to display people ordered by longest segment rather than total segments, and released it as Version 1.5.1. I’m looking forward to giving the workshop. We’re ...

Match Categories at FamilyTreeDNA - Fri, 14 Jul 2017

One option I didn’t realize existed at FamilyTreeDNA until Jay Sage alerted me. You can selectively hide or show the people whose matches are deemed “Immediate”, “Close”, “Distant” or “Speculative”. Here’s Jay’s instructions: In the upper-right corner of the home screen, mouse over the ...

A Pet Peeve - Say the Words: “GEDCOM” and “GEDmatch” - Mon, 10 Jul 2017

It is very true. The English language is full of inconsistencies. And one of these inconsistences is the pronunciation of the letter “G”. There is the hard “G”, as in: great, gallop, flying, guppy and goat. And there is the soft “G”, as in gentle, giraffe, gem or gymnasium. Hard “G”s ...

Do you #Genchat? - Fri, 7 Jul 2017

Is it true genealogists have more fun? Unfortunately I had to miss #genchat on Twitter last night. The questions and answers this week were about DNA testing, starting with MRCAs and then branching out. For those of you who do not know what #genchat is, it is a genealogy based Twitter chat that happens every ...

The Pickholtz-Diamond Index of DNA Ashkenazi Jewishness - Tue, 4 Jul 2017

Some of the least reliable information provided by DNA tests are the ethnicity percentages, also called admixtures. After getting my and my uncle’s DNA test results, I posted my ethnicity results. Our Ashkenazi Jewish percentages came in at 79% and 89% at FamilyTreeDNA and my result came in at 83.8% at ...

False Small Segment Matches at GEDmatch - Sun, 2 Jul 2017

I just happened to come across a post by Patricia Greber which showed the back of her T-shirt that she made to wears at genealogy conferences. Her shirt shows her family names and GEDmatch kit number and asks: “Are we related?” Patricia obviously wants other genealogists to see this, so I checked with her ...

Back From Vacation - Tue, 20 Jun 2017

I had a wonderful two week vacation with my family at Disney World in Florida. I don’t know if I’d call it relaxing, because it was non-stop go-go-go. Here’s one of the many amusing items from the Haunted Mansion for my genealogy friends: So it’s back to try again to finish version 1.3 of Behold and ...

Getting Carried Away - Sun, 21 May 2017

I’ve noticed it’s been almost 2 months since my last blog post, and that’s too long. I kept delaying my posts with the hope and expectation that my next one would be announcing the release of Behold 1.3.  However, the changes to Behold have been taking longer than I hoped. With Spring bringing ...

Raw Data Comparison: FamilyTreeDNA vs MyHeritage DNA - Tue, 28 Mar 2017

Before I leave DNA and get back to Behold for a few weeks, I had one more set of results I wanted to report on. A couple of weeks ago, I compared my MyHeritage DNA ethnicity results to my FamilyTreeDNA results, and also compared my match results. There was one other comparison I had wanted to do. It’s to ...

Done and Onward - Sun, 26 Mar 2017

What a few months! Finished up RootsTech and left with 3rd place in the Innovator Showdown. Took a much needed one-week vacation with my wife. Finally got out of my boot and started driving again. And I finished DMT’s new website at www.doublematchtriangulator.com and last week released version 1.5 of DMT. ...

My MyHeritage DNA Results Have Come In - Sun, 12 Mar 2017

First off, that didn’t take very long! At RootsTech, just over one month ago, I took a DNA test at the MyHeritage booth. I didn’t have to mail it back. Instead the MyHeritage people delivered all the samples they collected at RootsTech directly to the lab in Texas. A couple of weeks before RootsTech, I was ...

Heavy Lifting: Building a New Website - Sat, 11 Mar 2017

I knew it wouldn’t be easy. But I scheduled yesterday, March 10, to be the launch date for a website for my Double Match Triangulator program. The new website is here:  doublematchtriangulator.com There’s a lot involved in preparing a new website, even if you’ve done a few before. To be honest, I ...

What RootsTech was Like for an Innovator Showdown Finalist - Sun, 12 Feb 2017

Just back from RootsTech and what a week it was! As one of the ten semi-finalists in the Innovator Showdown, and the ultimate third place winner, I had some extra special experiences that I’ll always remember.   Pre Roots-Tech Even before I entered the contest, I was planning to go to this year’s ...

My RootsTech Tech - Thu, 2 Feb 2017

Several others have already written about the items and the Tech that they’re taking to #RootsTech. Nichole Dyer wrote about 8 Tech Tools to Bring to RootsTech. Alona Tester gives a big list of her general stuff and techy stuff in RootsTech 2017 – Counting Down. Christine Woodcock gave her list in ...

Non-Matches by cM - Wed, 1 Feb 2017

Roberta Estes did the first analysis of this and asked someone to do the same thing for an endogamous population. I had that data and I felt I wanted to know as well. I did a blog post about it a few days ago that I titled Double Match Phasing for an Endogamous Population, but using the term “Double Match ...

My #RootsTech 2017 Schedule - Sun, 29 Jan 2017

I finalized my schedule for RootsTech about a week ago (have you finalized yours yet?) of what I plan to do. I’ve put it on my online RootsTech App as well as on OneNote on my Phone in case the wifi at the Conference is spotty. If you want to track me down, this is where I’ll be: Monday, Feb ...

Triangulation, Single Matching and Double Matching - Fri, 27 Jan 2017

It seems like my last post was a bit confusing to many people. I expect that the way I drew the boxes (to be segments) and the way I connected them with lines (indicating matching) was not intuitive, and it did not allow people to see that Double Matching with two people actually triangulates. I’m going to ...

Comparing Single Matching to Double Matching - Wed, 25 Jan 2017

Important Note:  After this article was written, I found many people had trouble understanding the concepts, as the diagrams were confusing them more than helping them. This article has been completely rewritten (just two days later) and uses a different diagramming that is akin to ...

Double Match Filtering for an Endogamous Population - Sun, 22 Jan 2017

A few days ago, Roberta Estes posted: Concepts – Segment Size, Legitimate and False Matches where she compared a child’s matches against those of her parents. She downloaded the Chromosome Browser Results (CBR) file from FamilyTreeDNA for a set of parents and a child, and then explained how she did the ...

DMT is a semi-finalist in the #InnovatorShowdown at #RootsTech 2017. This is a new version of the program with several improvements. You can get the new version on my DMT page. It is freeware to help you do  autosomal DNA segment analysis. Now Works with Older CBR files My own FamilyTreeDNA results ...

GEDCOM 1 Lives! - Sat, 14 Jan 2017

I found out about this On December 29, when Martin Geldmacher of Germany requested a trial key for Behold on the Behold Download page. He wrote in the “Please let me know how you found out about Behold” box the following: I am trying to find a way to read/convert an old Gedcom 1.0 file (created by FHS). ...

What to do When Your @FamilyTreeDNA Autosomal Results Come In - Tue, 10 Jan 2017

It’s always an exciting day when your DNA results come back. After analyzing my uncle’s results ad infinitum for the past six months, I finally bit the bullet and sent away for my own test. The FamilyTreeDNA Holiday Season sale with coupons for extra dollars off was quite motivating. I ordered my own test ...

One More #RootsTech and #InnovatorSummit 2017 Pass Giveaway - Mon, 9 Jan 2017

20 Years on the Web - Sun, 8 Jan 2017

Yesterday was 20 years from the day I put up my first official web pages in 1997. (Rats. I missed it. I should have had my web-iversary in my appointment calendar.) I started webhosting using the services of Concentric.net who in 2000 were acquired by XO. My original web address was: ...

Digitizing and Going Paperless - Thu, 5 Jan 2017

When I was reviewing the #RootsTech 2017 Schedule several months ago to see what sessions I would be interested in attending, I was particularly attracted to the talk by Janine Adams and Brooks Duncan on “Go Paperless: Digitize & Streamline Your Research”, on Friday at 11:00 a.m., described as: ...
