says Elizabeth was from Sauterstead ....you say born 19th Jan 1715 in Torver 
- this would mean Richard was 29 and Elizabeth 14 

   when they married - IT IS POSSIBLE - but I would have thought unlikely...maybe a bit more research is required 
I have posted the 1699 marriage in Broughton - IN CASE they are Richards parents ??  they look more likely to me
