17.3.1799 mrs Foulkes, SC, EM at Holcroft's / mrs Curson calls 25.5.1799 / S Curson calls 27.5.1799 / S Cuxson at tea 29.5.1799 / call on mrs Cuxson 2.6.1799
The two Curson entries were clearly Godwin's misreading (the cataloguer of the Abinger manuscripts has made the same mistake) of the name in the letter (Abinger c14 f76-7) in which S Cuxson asked Godwin to comfort an afflicted being for an hour or two. Dated Friday evening it fits best with the call of mrs Cu(r)son on Godwin on Saturday 25.5.1799. In another letter (Abinger c14 f78-9) (s)he asked him to keep a secret. The GD website editors guessed that Cuxson was male because of the many calls on Godwin apparently made alone. I reckon Mrs Cuxson, Cuxson and S Cuxson are the same person. Godwin may have met her earlier at Holcroft's (first entry above) as I can think of no other likely SC. (EM was perhaps Elizabeth Mercier or Elizabeth Marshall, not likely Elizabeth Mansel as she was married to Frederick Reynolds the day before). Mrs Foulkes may have been her friend and may have recommended Godwin's counsel to her (see my blog on the Reveleys and the Jenningses).
There were Cuxons in London and in several midland counties but the spelling Cuxson seems to have been confined to Shifnal, Shropshire and nearby. Richard Cuxson married Sarah James on 7.1.1769 at Withington and/or Stirchley, Shropshire. R Cuxon was a Land Tax commissioner for Shropshire in 1785, and Richard Cuxson and Mrs Cuxson were both assessed for Land Tax in 1798 at Shifnal. The will of Richard Cuxson was dated 7.7.1801 and proved at Lichfield 9.9.1801, one legatee was John Cuxson grandson of Richard's uncle Hugh. John Cuxson was an attorney articled to William Willey of Basinghall St London in 1788, and on 27.5.1790 his sister Elizabeth Cuxson sp of St Michael Bassishaw London married Stephen Thibaud, witnesses John Cuxson, Anne Cuxson, Lucretia Moultrie, Sarah Moultrie, Ann Willey. The Moultries lived at Aston Hall near Shifnal and John Moultrie sr Esq of London was buried at Shifnal in 1798 aged 70 (he had earlier been Lt Governor of Florida). John Cuxson practised as an attorney in London but went back to Shifnal, married Eleanor Roden there in 1812, and was recorded as attorney of Shifnal in 1824, two of his sons went to Oxford university. His father Thomas's will was proved at Lichfield 1772, his mother's name was Ann, and his grandfather Hugh's will was proved at Lichfield in 1779.
Sarah Cuxson was the only Cuxson in Lichfield wills or Shifnal registers with a first name beginning with S. She would have been about 60 at the time she visited Godwin (if it was her). The plural Cuxsons probably included John, and on 31.3.1800 Godwin took tea at Cuxson's and noted (Henry). I have found no Henry Cuxsons in wills or registers. When J Cuxson called on 5.2.1801 there had been no Cuxson in the diary for 11 weeks, a much longer gap than any time before excepting when Godwin was in Ireland. The four more Cuxson calls in 1801 were probably John Cuxson as well, and Sarah had perhaps left London. Although most of her visits to Godwin were on her own, Godwin also saw her once with Mrs Boydell and twice with Mrs Rutton (see their entries). Despite these details the identification is far from certain and the Cuxsons' role in Godwin's life remains a mystery. It coincided with Godwin's interest in Sarah Elwes
