Attaching someone else’s DNA to your online family tree
Many of you, in fact almost four thousand of you, have already attached DNA to your online family tree. As you know, this translates into a much larger potential for people finding and connecting to your family tree. As more people add their results, the Ancestry.com DNA database becomes a powerful asset toward making connections and family tree discoveries. With 8.3 million family trees containing 810 million profiles, adding DNA results to a family tree multiples your chance of finding and making connections with genetic cousins and extending branches along your family tree. The four thousand DNA attachments spans over seventy-one thousand ancestors with inferred DNA!
I’ve received some comments on the blog about attaching “someone else’s” DNA to a user’s tree. This is not a difficult process. To have the DNA of another person represented in your tree, you first need to invite him/her to your tree. Here’s how:
-
After logging into your Ancestry.com account, find “view all my trees” in the “My Trees” menu.
-
Next, “invite family” to the desired tree. Be sure to assign a role of either “Contributor” or “Editor” to the invited person (this will allow him/her to both view and edit your tree and attach his DNA.
-
The invited family will need to accept the invitation and then login and attach his/her DNA to the appropriate tree. Should the other person need help, you could login on his/her behalf and attach the DNA.
DNA will be designated on the person profile page as is illustrated below (the first shows the profile page for one’s self and the second for an individual receiving inferred DNA propagated up the tree.)
Attaching your DNA results helps others find your family tree through DNA. Furthermore, attaching and propagating your DNA results will help others find and confirm a connection to your family tree.


I added my grandfather as an editor to my family tree so I could attach his DNA results to my tree. However, as an “editor” he is not allowed to see living people (that box is grayed out). So who does he attach his DNA to if he cannot see his own name?
