I though the other burial might have been her but no this is the wife of Peter Corkill."
It was niece Jane 1734-1802 who was married to Peter Corkill. Catharine who died 1784 was the sister of William Corkill of Ballagorry Mooar who married 1731 Barbara Kerruish, and Jane was Wm & Barbara's eldest child.
