Hi Joan
I have a hugh amount on the Wraight connection, although David Gadd who is in the US and may be already known to you has a lot more on the Gadd side, but on the Pavis side I have very little. Charlotte married William Gadd [born 1836] the Son of Harriet Gadd [Baptised Gad 1817] who was married in 1838 to William Wraight [baptised Wrate in 1818].
If you send me an e-mail -
berry.wraight@gmail.com - then I can send you a spreadsheet with the relevant info.
Cheers
Berry
