I'm trying to research my father's family, since he doesn't know much about his history. But I've hit a brick wall.

His father, Howard Roy McComb, possibly lived with someone other than his parents growing up. I found a possible John McComb as the father, but nothing after that. His mother, Anna Elizabeth Brown, was illegitimate. Her father was named George Hamer. No idea what her mother's name was.

Is there a good way to search for them that I'm just not seeing?
