John Blythe


17 Eliz John Blythe and Elizabeth his wife, holding the manors of Quarmby and Barnby upon Don, agree to convey it to trustees for the marriage (already had) between Thomas Blythe and Dorothy Kaye.
DD 12/II/11/2

A further assist is provided by the statement "Thomas son of Nicholas Blyth, half brother of John"

Eleven years later, John grants the remainder to William Blyth, then Anthony Blyth, then John Blyth all apparently brothers to each other, "in case Thomas and Dorothy die without children".  One could suppose that these were all brothers to Thomas as well but it's not stated.
