Hi Mary,
I have the feeling that we will soon be tracing the same family lines, although I can not prove it at the given time. I have recently acquired information that puts our families in the same area.
My g-g-grandfather, August, was also born in Katholisch, Rechberg, Waldshut,
Baden on 14 August 1864 and was christened there on 15 August 1864. I am thinking that Katholisch might actually mean a catholic record. Perhaps it does in your marriage record as well.
My g-g-grandfather's father's name was
Roman Weissenberger. Do you have that name in your tree?
