I don't know which of the two death dates for Regina is correct. In the 1880 Census, Conrad is listed as age 52 from Hessen. His wife, Maria is age 37, born in Austria. Their children living with them at that time were Elizabeth age 15, Joseph age 11, and Conrad age 8. So I think the 1875 date is the correct one, unless they were divorced. I'll try to find an official record. As for the priests, those notes are hand-written from Robert's personal knowledge, so I don't know how accurate they are. Will email you directly on other info.
