My mother's name was Mary Winifred Bell, daughter of Lilian Margaret ( or Marguerite)
Rumball and George Bernard Bell. This was a second marriage for him, he was a widower with a grown family when they were married. My sister has more info on the grown children, none of my mother's brothers were named Richard, however the name Bell seems to be very common there. Will send more info as soon as possible. Our family is here in Canada, emigrated in 1944. Rest of my mother's family is still in Newcastle. Does this help?
