Hi Joss

No I have not found the marriage of John & Katherine/Catherine
They also had a son William 24-9-1676
The Will of John 1640 he wrote it in 1711 it was proved 1718 in it there is no mention of William just Catherine John Thomas

Using John % Ruardean 1702 bap you should find
John Wilts/Wills 3-1-1702/3 plus [father described as John junior]

I agree Elizabeth 1729 - bur 1801 71yrs wife of John as young but plenty of men marry younger women, also their one witness was Richard Wilce and this above John had a brother Richard - one thing though - I don't have a copy of their marriage lic so it would be worth a visit to Gls RO or write and ask for a copy

I also don't have the marriage of Thomas 1680 - Hannah only a few words from a headstone.

bye for now Pauline
