My name is Bryan Hargan of Pickering, Ontario. My great-grandfather Alexander Hargan was born in Castledamph Tyrone in 1858 and lived in Gortin Tyroneto 1931. My grandfather Robert was born in Gortin in 1887 and came to Canada about 1910. I have not been able to find any links to my great-grandfather in Tyrone---any help would be most appreciated!!
