Did you know? New Y-DNA and mtDNA Database that is integrated with WikiTree. mitoYDNA.org

mitoYDNA, THE new Y-DNA and mtDNA Database is here. What is mitoYDNA? How can it help the genealogy community? How can it help WikiTreers? And many more questions, answered.

What is a Y-DNA and mitochondrial DNA database and why do we need it?

Y-DNA – is the DNA for males that follows the patrilineal line back, father to son, for a very long time – thousands of years.

mitochondrial DNA (mtDNA) – is the DNA that follows the matrilineal line back, mother to her children, which is passed on by only her female children to their children, for a very long time – thousands of years.

For years anyone who tested their Y-DNA and mtDNA could post their results to the databases YSearch and MitoSearch to do comparisons, matching and analysis. If you had a Y-DNA or a mtDNA test you could compare and match with people from various DNA testing companies. GDPR (General Data Protection Regulation) caused FTDNA to make the decision to close these two databases – time and money to get each and every person in the former databases up to the new privacy standards was too expensive and time consuming to attempt....

mitoYDNA ID’s appear in WikiTree and can be used to view comparisons on mitoYDNA.

Thanks for your work on this, Mags, and thanks for sharing the news here!

Does this site integrate/connect a person's claimed paternal- or maternal-line lineage with the lineage that appears for them on WikiTree?

Hey Ellen,

"Does this site integrate/connect a person's claimed paternal- or maternal-line lineage with the lineage that appears for them on WikiTree?"

It connects the DNA results posted to mitoYDNA to the Ancestors profiles via a WikiTree users entered DNA test information, which would include their mitoYDNA ID.


Here is a claimed direct paternal line in WikiTree that goes back 29 generations: https://www.wikitree.com/index.php?title=Special:Relationship&action=calculate&person1_name=Pierpont-94&person2_name=Pierrepont-45&gen=30. That line has a Y-DNA tester who is in mitoYDNA.

There is a claimed direct maternal line that goes back 13 generations https://www.wikitree.com/index.php?title=Special:Relationship&action=calculate&person1_name=Tillman-416&person2_name=Hamon-244 It has an mtDNA tester who is in mitoYDNA.

Done, thanks Mags and all who helped create this tool.

Just a note on the instructions.

  • Enter tester’s date of birth (this will likely get changed to a checkbox to indicate the tester is 18+ years).

has already been done.

Can you explain ways it might benefit me to add my test and/or other rdlatives tests?
by Veni Joyner G2G6 Mach 1 (16.1k points)

Hello Veni,

Not everyone has tested with Family Tree DNA, and so it allows comparison between different labs.  Those who belong to the same direct paternal line (or direct maternal line) should have sufficiently matching haplotypes (or mitotypes).  For example if you go to https://www.wikitree.com/wiki/Roberts-7104 , then next to the Y-DNA tester’s mitoYDNA IDs click on [compare] then if you are registered at mitoYDNA you can see this comparison of those two Y haplotypes: 


If you go to https://www.wikitree.com/wiki/Cook-7033 you can also perform an mtDNA comparison via WikiTree which is displayed at mitoYDNA.

mitoYDNA allows independent verification that the direct line back to the shared ancestor is accurate.

Sincerely, Peter

Peter, I tested with Family Tree DNA a couple of years ago, and in the last 6-8 months, I haven't been very active here. I want: first to "catch up", but now would you be able to explain the situation above and its readiness for those of us who are definitely BEHIND.  

I do have a German born father who doesn't know the identity of his paternal parent (his mom kept him, her lover, a secret). So I am ready AND willing to learn and to benefit by any or all of the new ways we can research our genealogical pasts. Would you be able to direct me, after I give you some of the basic information I do have about my father's heritage?
