Re: Voelker/Vo'lker 1864 Germany

Hello.This is a long shot.Am just beginning to research my husband's family.His grandfather William J. Voelker, b. 1865 had a brother named George.I don't know when they came over from Germany, but at some point they settled in Buffalo.Father of William and George was Charles Voelker.Any leads for me?Thanks.
