Glad to have got a reply. Yes, not a lot of time to do family history research when you're working!!
Yes, Fanny was the daughter of William and Harriet, and married Mr Piggot.
I could be wrong but I have them down as having eight children. As far as I know Eleanor married a William Brown, Ada?, Mary Elizabeth m someone called Richard ?, Alfred Henry m a Kate ?, William Evans m a Sarah ?, Walter m another Kate ?, Ethel m William Wilson, and Harold a Mabel Bloom/Blum.
My line is from a daughter who is often missed out, born in 1855, Ann. At a little after that time Harriet seemed to be with a John Brailsford, a labourer on the railway network, probably on the Settle - Carlisle Viaduct, she doesn't seem to have actually married him, although it seems that William Newbould may have died around that time. She later moved on to a Robinson!!
