DNA testing has determined that I am a 66/67 match with a Wilhite whose 6g grandfather was Johann Michael Willheit, the immigrant. FTDNA has indicated that there is a 95% likelihood that this Wilhite and I share a common paternal ancestor within 8 generations. My problem is that I do not know the identity of my most immediate Wilhite ancestor, so I am working my way from the past forward. Before I can do so, I need to know if Johann Michael Willheit had any siblings who also came to America. Is that information available? I do realize that later descendants of earlier members of this line might have come to America at a later time, but for now I want to concentrate on Johann Michael. Thanks for any help you can offer.
