The Grove/Graf side of my mother's family can be traced back to at least the 17 century. My poor ancestor
Martin Graf doesn't get as much as his brother Hans Graf/John Grove who was said to be the Baron von Welden in Alsace who had a fallout with some jealous parties and he went to America as a result.
My ancestor Christian Grove who moved to the Shenandoah Valley, VA is tentatively descended from Martin Graf. He was named in a will that Martin Graf made before his death.
My niece's family can be traced back to the 13th century from my BIL's side of the family.
