Carters 9.3.1797 at John King's / 28.5.1798 again / 8.2.1799 Carter at King's / 19.2.1806 mrs Carter dies / 16.9.1808 call on Carter / 14.8.1813 Carter at S(arah) E(lwes) / 11.10.1813 call on Carter / 8.11.1813 again / 24.11.1813 again / 1.12.1813 again / 6.12.1813 again
The mrs Carter who died 19.2.1806 was Elizabeth Carter DNB 1717-1806 and perhaps too respectable a "bluestocking" to have been a guest at John King's
John Edward Carter gent of Leicester was a party to the marriage settlement of Augustus Butler (qv) to miss Danvers, his will PCC 1813. Thomas Leveson Prescott, a naval officer who got involved in a dodgy banking scheme with John King in 1802 married Louisa Carter of St Giles Cripplegate on 10.4.1802 at St Marylebone, but the Carters Godwin met at King's were three to five years previously, so this is just a possible clue rather than a strong connection, especially as Carter is a very common name. Louisa Redfearn Carter was baptised at St Giles Cripplegate on 2.11.1780 daughter of Nicholas & Ann. Her father Nicholas (will PCC 1784) and his brother George (will PCC 1781) were prosperous butchers of Grub Street, St Giles without Cripplegate. Nicholas married Ann Newbank at St Giles Cripplegate 12.12.1758 and in his will mentioned his wife Ann, his daughter Elizabeth wife of Thomas Dalby, his daughter Ann wife of Bewley Morrison, and five unmarried daughters Sarah, Mary, Jane, Louisa, Dorothy.
