I have a birth record >from Vienna >from 1892 that states that the
father, Israel Wolf Traurig legally changed his name on April 1, 1873
(file number Z. 21869) to Israel Wolf Trauring. It also says Israel Wolf
Traurig was born in Pilzno in on April 21, 1869. As he was not even
4 years old, presumably that name change occurred in Pilzno, or in a
city nearby. Does anyone know if such a document would still exist,
and if so which archive I should be checking?
