I have the Will of Richard Corjeage of Kirk Michael dated 1795 (signed 1794) but can see no burial for him in Brian's index, so I wondered if some kind soul with access would be able to check the Michael burial register anyway just in case. I looked at Michael MIs recently but I didn't spot him. I'm really trying to find out his possible birthdate and hoped the burial register might give his age at death.
He married Jane Darcey in 1773 and had at least 7 children. It's just possible that he could be listed as Cavendish, but I would expect Corjeage (any number of spellings).
There is a Richard born 1738 but he would be 35 if he married Jane, 18 years his junior, and aged 54 at the birth of their last child. Not impossible, but I'd like a bit more evidence before I join up the dots.
