Here is one Allegheny County family with interesting name changes: James Halovanich married Johanna Fisher in Novigrad, Austria on 25 July 1903 They immigrated in 1898 from Bremen to Baltimore and lived in Rankin, Allegheny Co., both died in Pitcairn. They had 11 children, including twin boys. Edward and Frank who were the youngest children Edward (my nephews maternal grandfather) changed his name to HALAVAN ( as 3 of his siblings also did) Twin brother Frank changed his name to HALOVICH . The other 7 siblings maintained the name HALOVANICH Joanna FISHER's parents were Peter JANKOVIC  (American translation Fisher) from Adleski, Slovenia and Catharina POSEK, whose father was Nickolai POSHEG and her mother was a cousin, Maria POSEK. They lived in Allegheny Co. in 1900 but moved to Export, Westmoreland Co., PA. Are any of you researching these families? JoAnn Cupp Grass Valley, CA
