6.8.1807 call on Taylor (Vaughan) / 12.8.1807 Vaughan at S(kinner) S(treet)
The two Vaughan entries above probably referred to the same person. The previous use of Vaughan was 1798 and the next was in 1810. Godwin seems to have been arranging for someone to sleep at his Skinner-st shop, so on 7.8.1807 Hooley sleeps 4 nights in S S, on 11.8.1807 Godwin himself sleeps at S S, on 12.8.1807 Vaughan at S S, so this Vaughan was probably someone paid to sleep there, possibly an apprentice or employee of Richard Taylor's.

The first six of the above entries are uncoded on the GD website, the rest are coded to a generic Vaughan person record. I agree with the editorial notes in that person record that W H Vaughan was likely the stationer William Hasleham Vaughan. All the rest of the above entries, apart from Vaughan calls in 1816, were probably William Vaughan DNB 1752-1850. This was probably someone Godwin felt might help him raise money, and appeared in the diary more than once next to Ward. Solly, H Rogers, and R Sharp, all people who knew Godwin from back when and might have helped him raise money. The 1816 caller could have been W H Vaughan - or any other Vaughan.
