look at lib vas for Patrick Oct 1750 which refers to a deed of sale to John Kelly; in this lib vas entry the lands of decd John Kelly are transfered to son John names John senrs wife as Cath - deed is almost certainly NSS May 1738 6 but as of yet not looked at this one - wife Cath probably Cath Corrin m Patrick 17230125 but the deed might give her name
The wills of Isabel Kelly 1767 + john 1741 might well help (summarised in usual place on MNB)
