Hi Emma
Thanks for looking it up for me.
Marian Thompson seems to have different birth years in different census etc. She could have been born, I suppose, any time between 1826 & 1844. Are you able to have a quick look at other years for me. She also had a brother, John Charles THOMPSON, again supposedly born in 1838 in the same district, but this also may be some years either way.
Anything you can find on these Thompsons would be helpful.
Many thanks.
