Hello. Nice to hear from another Welzenbach researcher. I had e-mailed someone named Gary who is in this forum because I ran across an 1880 census from Maryland where the census taker had misspelled the name as Wilzenbach. I have run across my family misspelled in the same manner. I don't have the printout still, but I do remember there was a Casper on it. I am not sure when the name switched from a Z to an S, but I have the feeling that my particular family line has died out. Have you collected alot of Welzenbach data? I am missing a John Welsenbach(or Welzenbach) born in 1875. He might have worked for Singer Sewing Co.
