I found Regina (M. Regina = Maria Regina) in the records of Wiesthal, page 161. Her father is Jois (Johann) and her mother Eva. Godmother is Eva Bopp. I have also Fleckenstein ancestors, but I cannot find Regina in my database, there are too many couples "Johann and Eva" and we cannot decide where the children are belonging to. Probably you have more information about the descendents of Regina?
