I am wrong about Edmond/Edward Kneen.
I have just read the Wills of John Kneen & Jane Kneen als Camaish.

Jane's Will says.
hath decreed her only Child, namely John Kneen, Administrator.

This is affirmed to be the last will & Testament of John Kneen Sen’r of the Town of Ramsey.
He left to his son John Kneen all the Cash or Money he had in mortgage in Ballnisaig.

Averil.
