D Campbell 8.2.1799 at King's / 26.10.1799 again / 29.12.1799 Campbells at Lanesborough's / 19.1.1800 again / 16.3.1800 mrs Campbell at King's / 4.4.1802 again

Perhaps Donald Campbell DNB 1751-1804 whose will PCC 1804 dated 5.5.1804 mentioned his reputed son William aged 2 or 3 years and Augusta Kendall, probably the mother. His legitimate son Frederick William is also in DNB 1782-1846 so could have been included in the plural Campbells as well as his mother Mary whose dates are not given in DNB

Hodson 1.2.1799 at Mrs Fancourt's with Vardons & Chandler

Just possibly Septimus Hodson DNB 1768-1833. See also Hudson, printer in Bonney Diary dataset, and Hodgson, William for examples of how frequently these names were confused.

Arabella Hunt 30.1.1799 at Ralph Fell's

mrs Palmer 30.1.1799 at Ralph Fell's

Given that the Dignums were at Fell's maybe Mrs Palmer was an actress or singer. Highfill Burnim & Langhans have Ann nee Sharp, Mrs William Palmer whose husband died in 1798 and the Drury Lane Fund Book noted her death in November 1813, but there was no notice of her performing after 1787.. Drury Lane was where Dignum performed

see Correspondence of Mary Hays p504, Mary Reid born Leicester sister of John Reid DNB 1776-1822, whose will PCC 1822 didn't mention a sister

Mlle Le Canu 29.01.1799 (& Mary Hays & miss Reid) / 8.6.1799 E Le Canu calls (not in) / 14.6.1799 E Le Canu calls
