Shelley’s great-grandfather, John Shelley† a London alderman probably of Hertfordshire origins, settled in Sussex after marrying the heiress to the manor of Michelgrove, in Bramber rape, in 1474, and represented Horsham in 1491-2.
Shelley has sometimes been confused with a namesake from another branch of the family based at Patcham, near Brighton.
Shelley was described by Buckhurst as ‘zealous in religion’, but it seems his zealotry was of a conformist kind.
Shelley received 12 committee appointments in the first Jacobean Parliament, but made no recorded speeches. In the 1604 session he was named to consider the twice committed bill promoted by Sir Henry Neville II*, Buckhurst’s son-in-law (14 May and 14 June).
Shelley seems to have been in poor health from at least 1612, which probably deterred him from seeking re-election in 1614.
