Mary J. Fenton
born April 1882–April 1887
  in Rainton, Co. Durham
died very roughly 1955

1891 census: Living on Back Double Row, Quarrington Hill with parents, siblings, and boarders. Age is 8, and place of birth is Rainton.

1901 census: Living 11 Spencer's Bank, Whickham with parents, siblings, niece, and boarders. Age is 14, and place of birth is Rainton.

The disparity in the ages between the 1891 and 1901 census records is big enough to make one wonder whether these might be two different individuals.
