Marilyn, You ask a couple of questions for which there are no good answers. Anna Maria ??? Probably it was Blanckenbuehler on her baptismal record. Who is going to look for that name? Not many. If you choose one of American spellings, I would pick Blankenbaker which is the most common variant in America. As to where she was born, we can all agree on Neuenbürg or Neuenbuerg. At the time it was in the lands of the Archbishop of Speyer. Later it became Baden. Today it is in Baden-Wurttemberg (note the spelling). It is a difficult question to answer. Probably some standards need to be set. John.Blankenbaker@comcast.net
