Thomas Woodson

Individuals who descend from the same paternal lineage have the same Y-DNA short tandem marker profile

The Science

Two types of DNA markers are used by genealogists to trace family lineage: mtDNA markers and Y-DNA short tandem repeat markers.

Thomas Jefferson and Thomas Woodsons Y-DNA profiles were obtained in 1998 during a DNA investigation to prove the legitimacy of Thomas Woodson.

This web app compares your Y-DNA profile to Jefferson and Woodson to see whether you descended from the same lineages.

Frequently Asked Questions

Do I need to have mtDNA and/or Y-DNA makers to use this free web app?

Yes, DNA Access works with user accounts. If you have already taken the mtDNA and Y-DNA STR test, you can simply sign in to your DNA Access account to view your match results on the web. If you have not tested your mtDNA and/or Y-DNA STR marker, you will need to create a DNA Access account with the registration key on your test kit.

Who performs analysis on my DNA data?

DNA Access performs analysis on your DNA data. To get more markers, upgrades can be ordered directly from your DNA Access user account. All prices shown are in U.S. dollars, and all orders will be charged in U.S. dollars.

I am a female, can I still match against the Y-DNA profiles in this web app?

Both males and females can take the mtDNA test to trace their maternal line. Only males can take the Y-DNA test to trace their paternal line because only males have Y-DNA. For a female to trace her own paternal line, she would need to test a paternal relative, such as her brother, father, paternal uncles (father’s brother), paternal male cousins (father’s brother’s sons).
