Hello again. Robert Garrett from burial records he was buried (Grave 677) in Lezayre on 4th Feb 1792 (inscription states aged 61 years). Wife Catherine (Caley) was buried 16 January 1807. This is definitely the right Robert Garrett married to Catherine Caley, just confused over the dates of birth, I have looked at the will of William Garrett and Mary Kewn who had a son Robert - could they be his father and mother. It really is a minefield.
I find it odd to have grave inscriptions at this time, would the dates be confused on the inscription
