Further to the message I posted yesterday.
I realize that all previous messages are a couple of years old so the information I have may not be relevant any more but I have now found the marriage certificate of Elizabeth Stather.
She married George Thornham on December 25th 1845 in the 'parish of North Cave'.
Her age is given as 20 - George is 21.
There is, however, no mention of her father or his occupation.
They were married in the Parish Church.
They were married 75 years.
