FGEB V9p7 The name Dylyngham (sic) first
appears in the surviving Dean records in the year 1448, when a
Thomas Dylyngham is mentioned in a land grant relating to lands
in Bolnhurst, Pertenhall, Keysoe, and Dean. There is no proof
that this was the grandfather of John Dillingham. Winthrop
Alexander pg 3 "The earliest record of a Dillingham was
found in the list of intrantes, or persons admitted
as inhabitants, in Canterbury, when John Dillyngham, tailor, at
Westgate in 1433 and 1434, paid an annual fine or license of four
pence. The earliest connected records which enable us to
establish anything like a pedigree are found in Bedfordshire in
the latter part of the sixteenth century. The family then appears
in the Parish of Deane, in the northeastern extremity of that
county, and evidently must have been located there for many years,
being landowners and people of prominence." [DILLIN.GED]
