Mo, In History from Headstones there is this entry:
Carnmoney CI, Carnmoney, Antrim
LAUGHLIN,
The family burying ground of Henry McLaughlin, Belfast (no information)
I don't understand why it says McLaughlin, but Belfast I can understand, because Carnmoney is so close to Belfast, but I think you should send for Henry's death certificate, as that might contain the odd clue. Have you the birth certificates for any of his children?
