The sickly only son of the rakish poet earl of Rochester, Wilmot had early on displayed symptoms believed at the time to be the king’s evil (scrofula). He was touched for the condition by Charles II, but it seems more likely that he was in fact a victim of congenital syphilis.
Wilmot succeeded to the earldom aged just nine, following his father’s much publicized death in the summer of 1680. Under the terms of his father’s will he was entrusted to the guardianship of his grandmother and mother.
