Two members of Selham’s family had represented Reading in Parliament in the late fourteenth century, and he may have been the grandson of the second of these, Thomas Selham†, the MP of 1397.
Selham’s parents had held a house and land further up the Thames valley at Streatley, under the terms of a settlement made by Thomas Ropkyn and his wife. The Ropkyns’ grandson William, a glover from Reading, made a quitclaim of the same property to Selham himself in March 1443, and a few days later Selham pledged Ropkyn’s admission to the freedom of Reading. In the autumn the two men handed over all their holdings in Streatley to feoffees, headed by the mayor of Reading, Edward Linacre, and including David Gower*, who was already a feoffee of Selham’s house in London Street.
