many thanks Al and Wendy for your help with this one, your info is helping me build up a picture that hopefully i can work on and come up with some positive results.
Wendy, thank you for taking the time and trouble to get the information on richard and susannah for me, im sure it will all prove very helpful.
i think that the William you picked up on the 1851 leics census wd be too young to have been richards father but he may well be a relative.
Al, i think you are right i will have to take a good look at the measham parish registers, i will have to make another trip northwards and visit the leicester record office at some point and see what i can come up with.
many thanks again for your help.
