Where do you get the two marriages from?
In my Lincs marriage index-
1) a Richard LAWRENCE married an Elizabeth WALKER in Stow in 1800
2) a Richard LAWRENCE (wid) married Ann CUDBED (wid) in Coates by Stow in 1805
Children of Richard and Ann at Stow (from IGI) -
Charlotte 1806
William 1809
1841
Stow
Richard LAWRINS? 65 Tailor
Ann 65
Both born Lincs
Richard LAWRENCE was buried at Stow 10 May 1850 aged 74
1851
Stow
Ann LAWRANCE (wid) 74 Proprietor of Houses, Notts Thorney (5-6 miles south of Stow)
Charlotte WARD (dau,wid) 44 Stow
Henry WARD (gr son) 11 Wellingore
I don't doubt that
your Richard LAWRENCE lived in Stickney. I have serious doubts in believing that he was the one born in Stow (which, incidentally, is over 40 miles from Stickney).
