This MP was perhaps a descendant of a namesake who had represented Hastings in Parliament in 1377 and 1385, and a kinsman of Robert atte Clyve, a Portsman of Hastings who was exempted from taxation on his chattels at Fairlight in 1432.
Clyve, always active in the administration of Hastings, was sent as a delegate to Brodhulls on 13 occasions between 1440 and 1457.
Clyve is not recorded alive after 1463.
