Lucius Cary was a prominent English statesman and philosophical writer who supported Charles I. He sold Aldenham Manor in 1642 and was killed at the First Battle of Newbury in September 1643.

The principal historical source gives the sale date as June 1642; another account describes it only as later in 1642.
