I think that's the route I'm going to take for both James and for myself (genetic testing, anyhow; given all my AI conditions, I've already spoken about seeing a geneticist for both of us, just in case something happens to me soon and I don't find out in time). But a DNA test will be something I can do tomorrow. I don't mind contacting people if I can find out things about my father's side. That's something important. There's just so much to know. I should get on that and order a test. :)
