How much does that cost? I do think it would be interesting, but on the other hand sometimes I feel like downplaying the whole thing and never talking about it at all. Unless we can somehow find the genetic parents in the future there are never going to be any clear answers. As far as I know, they don't want to be found.
My father was adopted by his father (he was illegitimate and there was a marriage later on), and when I was a kid in girl scouts and did my family tree we just included the info of the adoptive grandfather. I guess I didn't really have any opinions on it one way or the other. It did give me more insight into my grandfather and where "he" came from, but that's about it. Just a few years ago, my dad was going through some old papers and he and his wife came across an old photo, and his wife said "Hey, this person looks just like you." And my dad said "That's probably because he's my birth father." But he had no interest in looking at the picture or finding out more about the person, claiming that his adoptive father is his father, and that's all there is to it (my grandmother had been very hush-hush about the topic, never even saying a name). Interesting how different people approach the same topic. DD knows her basic background, but doesn't seem to care and never talks about it.
