DNA TESTING AND GENETIC GENEALOGY

 When I started my serious genealogy research in about 2005, genetic genealogy was in its early stages. Family Tree DNA (FTDNA) was specifically established to provide DNA testing for genealogy purposes. So, in 2006, I ordered my first DNA tests.


Over the years, I have found some near cousins and assisted distant cousins in finding our most recent common ancestors. These connections have occurred on both my paternal and maternal lines.


As more people reviewed their DNA results and new company’s joined the genetic genealogy community, especially Ancestry.com, 23&Me, & YFULL.com, more matches started appearing. One of the most important improvements included FTDNA accepting results from other DNA testing companies. This provided a path to expand our comparison of DNA results.


So, we started a project at FTDNA – for both women and men. Here is the link to the project.

Examples of DNA Connections 

There have been many connections based on some matching DNA results. For example, I have found paternal ties to other Scottish lines, including MacCaskill, McKenzie, & Seaton. Thus far, I have not found DNA ties to ancestors of my 3rd great grandmother, Mary McLean (married to John McCrummen in 1804, North Carolina).

YDNA Branch: I1

In the I1 branch, there are additional sub-branches. The I-Z73 includes men currently living in Texas, Alaska, and Scotland. The I-FGC15560 branch includes ancestors of men from Isle of Man and Norway -  the time to a most recent common ancestor about 1000 to 1500 years ago. . Additionally, below the 

I-FGC15560 branch, we have discovered the I-FGC15537 sub branch. This branch includes men currently living in North America and in Scotland. 

YDNA Branch: R-M269

In the R-M269 branch, the YDNA tests are limited, so its sub-branches, for MacCrimmon men, are not currently known.   

FAQs

  1. Can anyone join the FTDNA project?  Yes, either male or female.
  2. What if I have a DNA test from Ancestry.com  or 23 & Me- can I transfer results to FTDNA?  Yes. These two tests are autosomal DNA. At Family Tree DNA, this is called Family Finder. The files from either Ancestry.com or 23 & me can be transferred. At the time of transfer you can also join our project.
  3. Where can I find the YDNA tree?  Without cost, go to either of the following:

Founded in 2005, The International Society of Genetic Genealogy (ISOGG) has extensive information on its site. “The mission of the International Society of Genetic Genealogy is to advocate for and educate about the use of genetics as a tool for genealogical research, and promote a supportive network for genetic genealogists.”   http://isogg.org
