Thank you, Donna. Those Mis have been very helpful, and they confirm that the Jane Kelly b 1789 was a second wife of Robert Kelly.
If Jane was a spinster when she married Robert Kelly, one possibility is Jane Cannon (bap 21 Sept 1789 Marown, dau of John Cannan and Eleanor Kelly ) who married a Robert Kelly on 25th Sept 1838 in Braddan. But if the Jane who married Robert was a widow, it would be very hard to identify her.
I was interested to see that the person who erected Robert Kelly's headstone was his daughter, Catherine Cannell. There's a baptism for a Cath Kelly 29th Oct 1815, father Robert Kelly, no mother's name. This would fit with a burial :
CANNELL, Catharine 90 Bra 6 Dec 1905
Dare I ask for an MI for this, please, Donna ?
