Thanks, Dolly.
I don't know if I can help, but if John died in 1749, and Elizabeth became a widow, she must have married John before 1749.
Looking in my IGI, before 1749, I can only see the following possible marriages to a John RAMSDEN.
3 Jul 1738, at Elland, to Elizabeth FARRAR.
8 Aug 1733, at Illingworth, to Elizabeth NEWTON.
28 Nov 1723 at Elland, to Elizabeth SMITH, although this one seems a little too early.
So, perhaps Elizabeth FARRAR or NEWTON, but Rishworth residents, usually married at Elland.
