I am looking for any leads on a Mary Ann Bearfield or Benfield, born in Gravesend, Kent, England in the early 1800s. Her father was Jospeh Bear/Benfield, an "oil man". She married a Mr Richards but in the 1840s, as a widow, married Joseph Dally. She was resident at Union Street, Lambeth, South London and they married at St Mary Newington. They had at least a daughter (Elizabeth Agnes/Agnes Elizabeth Dally) and a son, James Dally. They moved north to Stafford around 1850 and she probably died there in 1876. Any tips of this family or information on the origin of the Benfields generally? Thanks.
