I'm looking for the marriage record of William Higgins and Letitia McCartney, possibly of Glenavy. I found RC baptismal records for 4 of their children: Catherine 1851, Charlotte 1853 (both in Glenavy), William 1859, and Sarah 1861 (both at St Patrick's in Belfast). I'm also looking for other children born to them. Ancestryireland's index doesn't have the marriage record or any other of their children in their index of Down and Antrim records.
