Created a Baronet in 1641.299

Carew was the eldest son of the antiquary Richard Carew (1555–1620). He was educated at Oxford, probably at Merton, and studied law at the Middle Temple. He also visited the courts of Poland, Sweden and France, the first two as part of an embassy led by his uncle and the last in attendance on the ambassador, Sir Henry Nevill. He entered Parliament in 1614 as member for Cornwall, and subsequently also represented Mitchell in 1621-2. …The Civil War divided the family, and proved particularly fateful for them, for two years after Sir Richard's death Sir Alexander was executed on Tower Hill for treason as a Royalist, while John as a loyal Parliamentarian sat on the court that condemned King Charles and was eventually hanged, drawn and quartered as a regicide at the Restoration.299
