He was born on 12 March 1746, the only son of John Lethbridge of Westaway House in the parish of Pilton, North Devon, by his wife Grace Cardor, daughter of Amos Cardor of Westdown House in Devon. John Lethbridge was the only surviving son of Thomas Lethbridge, Gentleman, a lawyer of Clement's Inn, by his wife Sarah Periam, daughter of John Periam of Milverton, Somerset, and sister of John Periam of Milverton, MP for Minehead. John Periam in 1720 built a mansion at Sandhill Park in the parish of Bishops Lydeard, Somerset, which descended to the Lethbridge family. Periam was descended from Sir William Peryam of Little Fulford, near Crediton in Devon, Lord Chief Baron of the Exchequer under Queen Elizabeth I. Thomas had another son Thomas Lethbridge, Gentleman, who died aged 20 and was buried in the Bowchier vault in Pilton Church. Thomas Lethbridge was a younger son of Christopher Lethbridge, Esquire, of Westaway, by his wife Margaret Bowchier, daughter and heiress of Phillip Bowchier of Westaway. Christopher's uncle was Christopher Lethbridge of Exeter in Devon, Mayor of Exeter in 1660, and one of the Worthies of Devon of the biographer John Prince,. Mayor Christopher Lethbridge appears to have been the ultimate source of the great wealth of the Lethbridge family of Sandhill Park. The connection to the Bowchiers of Westaway provided the basis for a Lethbridge claim of heirship to the Barons FitzWarin, which had fallen into abeyance with the in 1636 death of Edward Bourchier, 4th Earl of Bath, though there is no documented connection between him and the Bowchiers. In 1786 John Lethbridge, the future 1st Baronet, made a generous gift of several thousand pounds to the Prince Regent "to relieve the Prince of Wales, out of concern for the dignity of the Royal family and the country and with no ulterior motive." However, it seems this gift was later used as a reason for the king to compensate the 1st Baronet by the grant of the title "Baron FitzWarin", alias "Fitzwarren". In 1809 he made an application to the king for the barony, and in 1811 his son wrote to the Prime Minister that this had been desired by his father "for many years", "as a mark of royal favour". A third application was made in 1812, but all without result. A Ledger stone survives in St Mary's Church, Pilton, to Phillip Bowchier of Westaway, inscribed as follows:
Career
He was educated at Winchester College and matriculated at Magdalen College, Oxford in 1764. He served as Sheriff of Somerset in 1788-9 and as a captain in the Somerset Fencibles in 1794, raised to meet the threat of French invasion. He was created a baronet in 1804, "of Westaway House in Devon and Winkley Court in the County of Somerset". He served as Member of Parliament for Minehead in Somerset from 1806–7, apparently due to the influence over that seat exerted by his friend John Fownes Luttrell, feudal barony of Dunster of nearby Dunster Castle, who "having incurred liability for a treating offence and to avoid risking a petition, returned Lethbridge as locum tenens until the danger of a petition was past". The Tate holds a 1785 portrait entitled The Lethbridge Children, presumably commissioned by him. The accompanying description states that he was a governor of the British Mineral Water Hospital in the 1770s and 80s.
Sandhill Park the estate of which lies partly in the parishes of Bishops Lydeard and Ash Priors, Somerset, built in 1720 by his grandfather's father-in-law John Periam who called it "Hill House". The subject of this article came to Sandhill in 1767, aged about 21, and it was in all probability at that time that the house was enlarged and the walls hung with pictures, including valuable examples by Salvator Rosa, Poussin, Guido Reni, Vandervelt, Snyders, Sir Joshua Reynolds and Gainsborough, and at the same time the library received its large collection of ancient books. The 1st Baronet spent lavishly on "adorning his place and mansion", as was reported by Lady Spencer, who related the following story :
Westaway, Pilton, Devon, sold by his son in 1819 to James Whyte of Pilton House.
Winkleigh Court, also known as "Court Barton", in the parish of Winkleigh, Devon. This manor was an important one in the county, being the caput of the Devonshire holdings of the feudal barony of Gloucester. It was at some time split into two moieties, but by 1822, when Lysons published his Magna Britannia, both belonged to Sir Thomas Buckler Lethbridge, 2nd Baronet. The Lethbridge family seat was near the church, but shortly before 1822 had been sold to Rev. John Tossell Johnson.
Marriage and children
In June 1776 he married Dorothea Buckler, a daughter and co-heiress of William Buckler of Boreham in Wiltshire, by whom he had one son and two daughters as follows.
Sir Thomas Buckler Lethbridge, 2nd Baronet, son and heir, several times MP for Somerset, who married Anne Goddard.
In 2010 Lethbridge was discovered to be the father of Claire Clairmont. It appears that Lethbridge had an affair with Mary Jane Vial Clairmont, who gave birth to a daughter on 27 April 1798 in Brislington, near Bristol. Births outside marriage then carried great stigma for the mother and child. Correspondence, including lawyers' letters, show that, after some pressure, he acknowledged paternity and made a financial settlement. Nonetheless, the child did not bear his name: the mother identified him as a "Charles Clairmont", adopting the name Clairmont for herself and both her children, to disguise their illegitimacy. A few years later, she married the writer and philosopher William Godwin, so Lethbridge's daughter grew up in a literary household with a blended family, including Godwin's stepdaughter and daughter by his late wife Mary Wollstonecraft. When the younger of these, Mary, eloped with the poet Percy Bysshe Shelley, Claire Clairmont accompanied them on their flight to Europe. Through Shelley, she formed an attachment to Lord Byron, and bore him a daughter. Thus Lethbridge was the grandfather of Allegra Byron.
Death
He died on 15 December 1815. On his deathbed he tore up a will by which he had disinherited his son. His monument in Bishops Lydeard Church is inscribed as follows:
