Luxie on Family Tree Circles

I am looking for relatives of Lawrence Corban. He married Martha Cox. they are my grandparents. I do not know much about my grandfathers family and would be happy if someone could enlighten me on their history. My mother was Irene Mary and she married Francis William Single. They had nine children Barry, Donald, Janet, Peter, Jill, Gregory, Wendy, Christine and Rosemary.
