I am also looking for Xavier (Xanier) Weiss Wittman. He was my Great- Great- Great Grandfather, and you apparently have more information about him than I have. what I have is a typewritten list that someone in the family had given to my Mom's Cousin, Sandy Campbell, who "found" Mom (Diane Barkus Lattery) two weeks before we found out that she had Ovarian Cancer and also that Gloria had died from it.
This is a cool website, It is also resposible for gettig me in touch with my ousin Dana Hilk. Write soon!
