My grandmother's father was Charles Lamberton and her mother Mary (Cambell)(died 1960's) That's all we know about her parents. When she married she became Elizabeth Barton. She had eight children, the last one being born in 1933. All were born in Derry. Their names are May, Elizabeth, Teresa, Agnes, James, Dorothy and Margaret (1 name unknown ). She left Londonderry and her husband! in the late 1930's or early 1940's to live in England. We know very little about her. She does have one remaining sister in Derry called Amy, married name not known.
