I am looking for anyone researching Freiderich Michael Speyrer who married Catharina Schloegel in Doerrenbach, Pfalz, about 1816. They had a son, Conrad, my great grandfather, and a daughter whose name I do not know. They both died when both children were young. Both children eventually came to USA. I am also looking for a local German researcher in the area of Doerrenbach or Speyer. Can anyone help? Many thanks !
