I am a descendent of Valentine through threeof his children, Isaac, Sarah, Henry. There is no proof that Valentine was born in the Schwarzwald, unless you have something new to tell us. Do you? I would love to hear any research that you have done. I have searched all of Zurich & Aargau Switzerland and Holland. there is still the Rhine valley to search, as the family may have moved up the Rhine to Holland before emigrating to PA.
