Thank you Ricky,
Don't I feel a fool. :-[I spent ages looking for them in the library. That is the right family. I think I (everybody else!!) have found all the family on the censuses and the IGI. I think the next step, some time in the future, is a trip to Lincolnshire Archives to look at Parish Registers and to see if I can go further back.
Thanks once again,
Louise
