Have just come across this info re Denis O Sullivan married to Mary Corcoran. The are my great great grandparents. He was known as the Master as he was a schoolteacher. Mary died in childbirth with her tenth child which was buried in the coffin with her.
Her sister Margaret was married to Denis' first cousin also named Denis. They are buried in Drishane graveyard. Go in the main gate and it is the first grave on your left hand side.
I believe my great great grandparents are buried only a few graves away....the headstone only lists their daughter in law and all deceased members of the O Sullivan family.
My great great grandfather became a chronic alcoholic after the death of his wife.
John O Sullivan.
