The German side of my family resided in the Fatherland at least since Roman times, AFAIK.
The other side is French (from the Alsace, surname Muller *grin*) with a memory of a Welshman in the line - remembered only for his bizarre name, Greenleaf Doubtit (It was always a side note when the name was mentioned that 'Doubtit' WAS as in "I doubt it"). This name has been literally passed down through the generations on my mother's side. Nobody knows who he was, or why the name anymore.
