I know everything about my father's birth - the date, place, his mother's maiden name (Gallaher), even her brother's name! Still, nothing. I've even met her! She divorced his father and remarried; won't tell us anything about the father.

Until I can devote a really large amount of effort into a search, which I can't, since I'm a college student, I'll just be content with knowing that my forebearers came from Prussia, the Rhineland, Switzerland, and Alsace.
