Tom Thanks for your response. I have a little more info to hand since my original posting. My Great Grandfather, Edward, was born in 1826. He married Anne Burleigh, date unknown, and I believe they had 7 children the last of which was my Grandfather Robert, born 31 Oct 1873. His wife Anne died in 1903. Do not know when Edward died.
Have some very sketchy info ref births during the 1800's but can not link your GGrandmother Mary Anne into the lineage.
I visit the old home area most years as I feel an affinity with the place. Have been through Derrylin many times which is about 8 miles from Druminiskill where my immediate family connections are. Have even considered retiring to the area but the wet weather tends to put me off a little.
With ref. to my GGrandfather Edward, I have not been able to make any sideways connections to his siblings and their lineages. Perhaps when I have more time and resources I will make more inroads.
