Hi Glynn, The only Irish birth I can find is this one.
Ireland Civil Registration
Name James May
Event Type Birth
Event Date 1 Dec 1848
Event Place Lahard, County Cavan, Ireland
Event Place Crahard, Cavan Union, Ireland
Father's Name Patrick May
Mother's Name Bridget Cumme May
James was born in County Mayo according to the 1901 census, but his father was called Patrick (Deceased) on the 1875 marriage certificate. Good find that one, James could have been mistaken when he did the 1901 census. In actual fact this is the only reason I know he was born in Mayo from the entry in the 1901.
