11.4.1807 M(arshall) calls for Adkins / 11.8.1807 Bow Street, w. Corbet & T(homas) T(urner), warrant ; Jo. H(odgkins) calls : Adkins calls : M(arshall) & T(homas) T(urner) dine : H(odgkins) & Adkins call ; Bow Street
The second entry above seems likely to have been Harry Adkins, police officer Bow-street public office (Holdens directory 1811 and in Old Bailey proceedings 1809 to 1819). So the first entry quite likely referred to him as well. A Harry Adkins was later keeper of Warwick gaol (1830s & 1840s)
1.3.1807 dine at King's w. Butlers, Mays, Supple, Italian Jew & mrs Hippisley; adv. Plunkets
All the guests listed by Godwin were Irish (apart from the Italian Jew). Supple was an Irish name and only appeared this once in Godwin's diary. There were some of this name living in London.
3.3.1807 at mrs Hippisley's, w. Wolsey / 24.2.1811 Wolsey calls / 25.2.1811 again / 18.3.1811 again
Despite the fame of Cardinal Wolsey this was a rare surname in Godwin's day. Wolseley was more common, and as the guests at mrs Hippisley's were of Irish connections, Sir William Wolseley (1779-1819) 3rd baronet of Carlow who died unmarried, is a possible, but I could find very little about him, and he seems less likely for the three calls in 1811.
8.3.1807 dine at Plunket's, w. Dolland
The only example of this name in Godwin's diary. Nearly all the Dollands in directories were of the Dollond optician family (DNB per.1750-1871), very often spelt Dolland. Old Bailey 15.2.1804 Barnard Dollond cheese and ham dealer 89 Strand. The guests at Plunket's were mostly Irish and the name Dolland was not unknown in Ireland but I found no likely candidates.
