I do have an Elmer J. Dornfeld, b. 1902 d. 1997. His mother was Elenor Richert, born in Martinville, New York. Elmer's father, Paul, is the brother of my great-great uncle Carl Dornfeld so I think we have a match. I've been trying to help other Dornfeld branches as well so this is good news. I'll look forward to hearing from you. Thank you so much!
