I am looking for any descendants of Joseph Fraser or his son James who emigrated to Philadelphia from Liverpool in 1887. They were born in 1835 and 1862 in Lisburn, Co Antrim, Nothern Ireland, but put "English" as their nationality on their papers. I believe that they may have gone to work at the Cambria Iron Works, and may have lived in Cambria City. Any leads would be welcome. Thanks.
