Hi AllanThe 51 census gives Mary's birth about 1792 which points to a different Mary Greenwood. Can't find her on the 61 though which is a shame as that would provide a check on birth year. One can only presume she died between 1851 and 61.There are 2 deaths for Rochdale Mary Waltons showing up on BMD (1857 and 1860) and 1 for Sept 1861 but that ones way after the census date of April 7th.
