On his marriage in 1596, Carey took up residence at Berkhamsted, which his father held on a long lease from the Crown. In 1602 he added to this property by purchasing nearby Great Gaddesden from Sir Robert Cecil† for £3,000.
Returned in 1604 to the first Jacobean Parliament for St. Albans, which borough he had previously represented in 1601, Carey left no trace on the records of the opening session. During the interval between the first and second sessions he was selected to accompany the embassy led by his distant kinsman lord admiral Nottingham to Madrid. Before his departure, it was reported (on 10 Mar. 1605) that he had been robbed of ‘£50 and three suits of apparel which were intended for the Spanish journey’, and therefore was compelled to pawn his jewel ‘in the fashion of a phoenix’ to William Pitt*.
Carey returned from Spain in time for the second session of the Parliament, in which he was named to one committee, for the repeal of a statute concerning unlawful games (26 Apr. 1606).
Carey died in London of smallpox on 8 Apr. 1609 and was buried at Berkhampstead, where he was remembered as ‘a most loving benefactor to the poor of this town’.
