Together with his wife Agnes, in August 1452 Morton took possession of lands known as ‘Whicchers’ in the west Sussex village of Yapton. These may have formed part of Agnes’s inheritance, for they had previously been settled by Henry Exton on his son John, with remainder to her right heirs, and it seems likely that she was the Agnes who had been John’s wife in the 1440s.
Although Morton was not a landowner of any substance he was styled ‘esquire’ when he witnessed deeds at Arundel in May and August 1469, so it is at least possible that he was accorded this status as a member of the household of Arundel’s lord, William, earl of Arundel – a supposition given weight by the fact that the first of these deeds concerned land held by feoffees to the use of the earl.
