Henry’s presumed brother, Benedict, served as mayor of Rye in 1361-2 and as bailiff of Winchelsea from 1368 to 1372.
Besides his property in Winchelsea (where he witnessed deeds between 1364 and 1386), Sely held land at Udimore, Ore, Guestling and Icklesham, on which, as a Portsman, he claimed exemption from parliamentary fifteenths. In 1392 a jury presented him for failing to maintain a bridge on his land at Ore. The date of his death is not known, but a deed of 1395 refers to a plot of land belonging to him as if he was then still alive.
