YourWalter Fyson from Wood Ditton may be related to the Walter Fissonmentioned in the book “The History and Atiquities of the Name and Family of Kilbourn”by Payne Kenyon Kilbourne, 1856. There on page 49, under “Extracts from the Parish Register of Wood Ditton, Co. Cambridge” is this item: “1574, Oct. 3 – Married – Walter Fisson to Joan Kilborne.” Joan Kilborne/Kilbourn was sister to Thomas Kilbourn (see below).
