The son of a Welsh judge, Thomas Overbury attended Queen's College Oxford (B.A. 1598) and the Middle Temple (1597). He was taken up by Robert Carr, knighted (1608) and involved in Carr's intrigues with Frances Howard, Countess of Essex. Overbury was imprisoned for opposing the match, and then poisoned by agents of the Countess. Carr and the countess were later pardoned amid great scandal.
