Notes:

He is the John Coate, eldest son of Marmaduke, named in his cousins will that was written in 1686 and proved in 1692. He received land in Wiletown from his elder cousin, John Coate. His brother William would have received it if he had died before 1692 when it was probated.

He can't be the John who died in Curry Rivel in 1710 because he is named in his sister Elizabeth's will in 1713 along with another brother named John.
