I guess you are my cousin. Edna Maitland was my aunt - though I never met her as she lost contact with my mother in the 1940's during the war. My mother was her younger sister Kathleen Charles was her older brother (b 1899). There were a total 14 children, 10 reaching adulthood.
I have a picture of what I think was your grandmother at her wedding. I think her husband was Harry Hammond? I can remember my mother saying she had two children.
I do have info on her mother's family. I would very much like to hear from you.
