he was buried age 66 noted as from Mount Rule at Braddan - 19 Jun 1857 which agrees with his ages in 41 + 51 censuses - however he or his family may well not have known his birth year if his mother died shortly after birth
However found I had photos of two wills
1788 John Caveen Arbory - decree - d 20 Jun 1787;unnamed bro + sis relinquished any right to admin;son Richard Caveen declared administrator
- this does not look like the John father of Ralph
the second is the 1815 will of John Caveen also in Arbory - [poor copy part of pages lost on photo] d 19 jul 1814;desired Ann Carran(w/o Wm Carran blacksmith castletown) + Catharine Clague(wife of john Clague Arbory) witnesses to state this was his last will + testament; wife isabel als christian exex with 1s to all other claimants

The marriage of John + Isabel was in 1790 and I suggested it might be a 2nd marr - the will suggests this as the 2nd wife gets everything
