Hey, thanks so much.

Ancestry is a site where you can take a DNA test to get your ethnicity results, and map out your family tree, meet other users who have DNA matches with you. However now that I think about it, there isn't much socializing besides the private messages and User Search feature. Maybe at most you would just be messaging a distant cousin who has a DNA match with you, on that website.

So I think it's better for me to go ahead and replace it with Mastodon which is more used and definitely is a social media site.
