Writing them and asking them to forward my letter to him sounds like the way to go. It worked once before when I was looking for my half siblings. That way, it's up to him whether he's comfortable getting back in touch with me or not.

Well... I learned something new about Google and doing searches. Never knew what "cached" meant or bothered to find out. Shame on me! LOL

Thanks, Petunia! I'll let you know if I hear from him.
