Re: diggle family history

Dear Diane,
A further thought (that makes the problem even harder to solve) - 'my'Sarah Schofield didn't have a sister Rachel. I'm not sure that were the surnames of the William and Thomas - were they Diggles as well? And was Charlotte also a sister of Sarah?
It seems hard to imagine that two completely different lines of Diggles and Schofields should meet up and intermingle!
