Hi Rowena,
May I suggest that you purchase that Marriage Cert as it may hold the key to your enquiry.
Reasons;
-- I have been unable to find William conclusively in 1841 census alone. There are a few married ones.
-- As he was in his 40's when marrying Ellen he may have been married before and you may have other Charlesworth relatives.
-- The Witnesses on the Cert may be relevant to your research.
-- If their is no Father named for him then we can be pretty sure Ann/Anne is his Mother.
-- It should say if he is a Widower etc.
Certs are are INCREDIBLY important to make sure we are following the right Family line.
They also often hold incredible info.
All I had on my G/G/G/Grandmother was that she appeared on the 1841 Census in Northumberland , born 1766, Scotland.
Her 1846 Death Cert said " Widow of Robert Reid, Weaver of Chirnside, Berwickshire, Scotland"
How amazing was that

Without that info I would have been unable to search further back.
I strongly urge you to get the Cert.
Cheers,
Trish
