I'm looking for my grandmother's mother and her family called Davis. My great-grandmother was called either Jane or Jennie Davis, born about 1882 and married Joseph Cray in 1910. She sisters called Alice (known as Charlotte) and Rose, and a brother called Arthur. There may have also have been other brothers and sisters - maybe a brother called Charlie? I believe all the family lived in Dulwich in the Camberwell district of London, and Jane/Jennie's mother may have originally come from Ireland.
