He was born 16 September 1597, the second son of Robert Carey, 1st Earl of Monmouth and Elizabeth Trevannion.[1] He was tutored within his father's household by Henry Burton.[2] He became groom of the bedchamber to Charles, then Prince of Wales, in 1616 and retained that post until his death.[1] In 1617 he was sent with Sir John Digby to Madrid and subsequently travelled in France and Germany.[1] When Giles Mompesson was expelled from his parliamentary seat of Great Bedwyn in 1621, he was returned at the subsequent by-election as the Court candidate despite his lack of local connections.[3] In 1623 he was sent to Madrid in the wake of Prince Charles and Buckingham.[4]
Between 1624 and 1929 Carey was elected for Cornish constituencies through the influence of his mother's links to the local gentry. He represented Helston (1624–25), Tregony (1625–26) and St Mawes (1628–29).[1] He was granted Sunninghill ParkinBerkshire by the king in 1630.[5] Carey was preparing to go on embassy to Venice, when his health failed and he died in 1634.[1] He was buried in Westminster Abbey.[1]
