My wife's family history shows her greatgrandparents were David Kaltenbach,(Koultenbaught) and Fredolina Wehrle. David was from the Grand Duchy of Baden and Fredolina was from Wurtenburg, Germany. Their parents are unknown. Some Wehrles settled in Ansonia, Connecticut but I have very little info on them. I do have a rather complete family history of David and Fredolina after coming to the USA. If there is any tie-in I wouldd be willing to trade info.
