Looking for my great grandfather james greenes family . Emmigrated in mid 1800,s to canada. Married elizabeth fleming . They returned to dungiven about 1870 and my grandfather william james greene was born there as was my grand aunt elizabeth . They returned to canada in mid 1870,s . James father was francis greene and mother was jane keown . Elizabeths father was john fleming and mother was sarah ross . As far as i know they lived and died in londonderry . Since they returned to dungiven in 1870,s , i assume they were from that area. They were prodestants . Any help will be appreciated. BILL
