I am trying to identify the mother of a Sarah PEARSON who married Frederick FENDALL (aka FELDON) IN 1841. Her father was JOHN PEARSON and I believe she was one of 6 children who were christened in Park Lane Church, Cradley between 1806 and 1818 and whose parents were JOHN AND HARRIOTT PEARSON; Sarah was christened on 15/12/1918.
JOHN PEARSON was 'deceased' at the time of the marriage of Sarah and in the 1841 census there is a PEARSON family in Mushroom Green, headed-up by widow Harriott; Sarah PEARSON put Mushroom Green as her place of residence at time of her marriage to Frederick.
I cannot find the marriage of John and Harriott to establish Harriott's surname before marriage - help!
