Thanks aghadowey.
We do not know if John and Mary Anne were in fact married. but there children were
Robert, James and Martha
Robert was born @1880
His children were James,(my Grandfather) John , Robert and others, Robert is the only living relative and this is where the new information came from regarding Martha and James
The only information I have of Robert is that given on his marriage cert, which stated Father John deceased. Living at Roe Park Tamlaght Finlagan, married at Drumachose Parish Church. June 12th 1913
Robert Died 1970's and is buried at Ballykelly.
He lived on the slate row, and then moved to the Drumrane road, His Son still lives on the drumrane road, (different house!) as does his Grandaughter (so the family really havent moved too far away
I'm fairly sure that The Ritters owned Roe Park at the time Robert was employed there ( He was a farrier) So I think the slate row cottage was a tied cottage.
The only other note:
On My Grandfathers birth cert : James McGee.. Father Robert McGee.
I'm just trying to find anything as this one is a hard nut to crack!
