Carpenter held a number of commissions in his father's regiment, the
3rd The King's Own Hussars, including
Lieutenant in 1708 when he was 13 and
Captain in 1712, but does not appear to have served. Regiments and commissions were then considered private assets, that could be used as an investment or to provide an income; their award to children was later discouraged, but drawing pay and delegating duties to a substitute remained a common practice. for establishing the
Province of Georgia In August 1715, he was made captain in the
1st Foot Guards, then
Lieutenant-Colonel in the
Life Guards in January 1730. Again, this did not require active service; although Guards regiments theoretically contained up to 24 companies, actual numbers were far lower and commissions often nominal. He was returned as
Whig MP for
Morpeth from 1717 to 1727; after inheriting his cousin's estate at Homme in 1733, he later sat for the nearby seat of
Weobley between 1741 and 1747. In June 1729, he was invested as a
Fellow of the Royal Society. In 1737, he submitted to the Society an account of a wound received by his father at the
Battle of Brihuega in 1710, when a musket ball remained lodged in his throat for nearly a year. In 1732, he was named one of the
Georgia Trustees, a committee set up to establish the
Province of Georgia, last of the
Thirteen Colonies in
British North America. The brainchild of
James Oglethorpe, it was an ambitious, philanthropic venture, which began life as a private enterprise but struggled to attract financial support and was eventually taken over by the Crown in 1752. Carpenter played a secondary role; he resigned in 1738, was re-elected in 1739, apparently against his will, before resigning again in 1740. When the town of
Brunswick, Georgia was established in 1738, "Carpenter Street" was named after him. He succeeded his father in the barony on 10 February 1731. This was an
Irish peerage which allowed him to remain a member of the
House of Commons. On 23 May 1733, he inherited the estate of The Homme (or Holme) in Dilwyn, Herefordshire from his second cousin, Thomas Carpenter. He died 12 July 1749 at
Grosvenor Square, London and was buried in the family vault at St Andrews, Owlesbury. His will, dated 31 December 1748, was probated on 24 July 1749. ==Coat of arms==
