I also have a Graham family from Armagh. My late husbands
great grandmother was Eliza/Elizabeth GRAHAM, born we think in Portadown Armagh in 1849, died in Gympie Queensland Australia in 1923. She married Arthur Farr in November 1871 in Seagoe Armagh. Her parents we think were James Graham and Margaret England.
So far I haven't had any luck tracing any other members of the family or any other information at all. Have you come across this family in your searches?
I would be most grateful for any information you could pass on.
