Hi Mary
I may have found your Mary but in case I haven't you may wish to follow my thoughts and look yourself as I am not familiar with the Worcester villages:
First of all Benjamin and Mary's marriage took place in Dec 1853 Kings Norton 6c 712 (you could of course order the certificate)

wife could be either Mary Lane or Walker.
In 1861 census Mary Hodgetts as she was as Benjamin's wife was born 1820.
In 1851 (before marrying Benjamin) there were no Mary Lanes born 1820 living in Kings Norton.
However, in 1851 there was a Mary Walker born 1820 in Kings Norton married to Joseph Walker. Source: HO107 2048 257 3
Could this be Mary's first husband who may have died and she remarried

If not, you could follow my train of thought and consider other villages around Kings Norton to find your Mary in 1851.

Good luck
Amanda
