I got really curious after reading the title of this thread, and tried googling some of my father-in-law's ancestors' names. Found my way into a couple of family trees connected with F-i-L's. F-i-L had no idea who his father was - at least, if he found out, he didn't share the information - but I have my suspicions from building up information. He was fostered (not adopted) after birth, so never actually knew his mother, either. However, with today's search, I've found some more information about his
mother's ancestors, which has filled in some gaps, so thanks for the suggestion, Sarah!
