I am researching my grandfather's line.He left Ireland around 1905 and married my grandmother, Annie in Caernarvon.He died as a p.o.w. in 1918.Patrick had a sister, I think Marie, who emigrated to the States around 1905?After my grandfather died my grandmother returned with three children to the castle(?) in Castlepollard where my grandfather had lived, possibly hoping for help? My father, also Patrick, was a police officer in England and died in 1998. I should be grateful if anyone knows anything about my grandfather.
