Many thanks for the response - I was beginning to wonder if there were any Weeder's left!
My great grandmother was Isabella Weeder, born in Crewe, Cheshire to another Isabella (father unknown). Isabella senior (confusing eh?) also had another child (again father unknown) called Richard who was born around 1865) She then went on to marry James Mogg and had at least another 5 children.This Isabella was the child of Charles and Anna (or possibly Annabella) and was born in Liverpool around 1840.She died in Derbyshire in 1898.
I don't know if there is a direct link - my details go back a bit further than yours, and I do not know what happened to 'our' Richard.
If it is of any help (or if there is a link) you could try the Derbyshire area for clues.There seemed to be a bit of an 'employment movement' away from Liverpool in the early 1800's into the Cheshire/Derbys borders.I assume you have tried the Mormon familysearch.com site?I would like you to keep in touch anyway, please feel free to e.mail me if you require any more info on my line or indeed if you have any info for me!!
