Now the two went to Pennsylvania and Ohio working at a coal mine around 1930-1938. Aftet that all traces of the two are gone. Both came to the U.S around 1912 -1914 according to Ellis Island. Is there any way to get census of Pennsylvania and Ohio in that time frame? These two might be a relative that i don't know about. Thanks for any help.....................................bob
