Here is the extra information about James and Mary Coxwell.
James Coxwell (1743-1787) was apprenticed for 8 years to a London apothecary, James Bromfield, on 7 June 1757. On 12 December 1769 he married Mary LeClere by licence at St George's Hanover Square, London. Mary was the daughter of Thomas LeClere, a surgeon of Newport, Salop. She was baptised on 10 Oct 1747 at Newport. Thomas LeClere married Anne Sansam on 30 Nov 1746 at St Leonard's, Bridgnorth. He died in 1769, and his PCC will was proved on 4 Oct 1769.
James and Mary had four children, all baptised at St George's Hanover Square: Ann (26.09.1770, died in infancy), Ann (19.03.1772), James (30.08.1773) and Catherine (09.07.1775, died in infancy). They lived on Lower Brook Street from at least 1772 (land tax records), and James practised as an apothecary. However in April 1782, he was declared bankrupt (London Magazine).
James died on 10 March 1787 according to a family tree on the Ancestry website, but I have not found any burial record, and no other details are known.
Of the children, James worked for the East India Company and was listed as Captain of various ships, including the Lady Raffles. He did not marry, and died in 1827 aged 55. He was buried at St George the Martyr in Camden on 31 October, and his address was given as New North Street. He made a will (PCC) in which he mentions his grandmother Ann LeClere, his nieces, Catherine and Ann Jones, daughters of his late sister Ann, and his brother-in-law, James Jones.
Anne Coxwell married a lawyer, Frederick Coningsby Jones of Gray's Inn, at St George's Bloomsbury on 4 June 1791. They had three children – Ann (1792), Catherine (1794) and Mary Margaret (1796).
