I suppose you have found Henry's birth in LDS
Henry Laughlin, born 28 March 1838 father Alexander Laughlin, mother Esther Ashton or Austin.
Coincidentally, if you look at Griffiths Valuation for the Parish of Templepatrick, close by, you will find an Alexander Loughlin renting a house in the townland of Ballyutoag (a stone mason would only rent a house, no land). In the same townland there is a James Kerr, renting 101 acres of land. Do you think these may be the parents of Henry and Elizabeth?
