10.2.1795 at King's / 27.3.1795 at Geralds (with King) / 1.4.1795 Godwin meets him before dining at King's. In Godwin's 1796 list for 1795, inserted above with King's other guests G Rogers, Anderson & Davis.
I found a Henry Kaines butcher of Dukes Shore, Limehouse, will PCC 1801, and a Thomas Kaines of St Marylebone buried 24.10.1827 age 65 at Countess of Huntingdon's Chapel, Spa Fields but no good reason it should be either of them except that the name is rare. Looked at variants Kanes, Caines, Canes and Keynes with no more luck
