Several things to consider. Forget the ethnicity estimates, it’s an emerging technology and sometimes can be confusing to people who don’t grasp it. Forget all of crazy stories like adding African ancestry to piss off racists. That came from an unsourced article in Cracked magazine.
Now you will get matched to other users. Some may be known to you. Some may not be known. You may find out some unsettling facts in your family. You may find persons who were adopted out as infants. You may find persons who were the result of an affair. It’s possible you could be of assistance in them finding their biological parents.
I have a friend who found out what happened to her ggrandfathers brother. They were separated as children during the Spanish Flu epidemic.
I found my biological father. My cousin found her biological father.
Some people find a half sibling they knew nothing about. Some people find that the man who raised them isn’t their father. Some people find out that they themselves are adopted.
So you need to weigh the pluses and minuses.
Oh interesting, thanks.
