Dear 100 Hour Board,
I've been doing some work for Relative Genetics (a company that verifies the genealogical research you've done with DNA testing) and it got me wondering about how adoption factors into genealogy. If you have been adopted, can you be inserted into the family tree of your adopted parent's, even though you're not biologically related to them. Does that then mean that you could possibly exist on two family trees--your biological one and your adoptive one? How does that work?
First of all, there are no set rules for how to construct and who is included on a family tree. It encompasses "family members", however you define that. So is it possible for you to be on more than one family tree? Absolutely.
If you are adopted, there is nothing wrong with being listed on both your adoptive parents' and your natural parents' family tree. Family trees are whatever you want them to be.
