Hello, Ed. Thank you for replying to my post. Since the time I made the inquiry, I have gotten more information on the Wieland family to whom I am related through Martin's half sister Hermina; this includes work by a genealogist in Germany who traced the entire family back several generations from Martin. I would be glad to share further information with you if you and your wife are interested and I would be happy to know more of your own research.
PS. I still have family in Austin and have visited the Dessau church and been to a Wieland family reunion when the mayor of Dessau Germany was a guest.
