My mother was also an Ellerker prior to marriage. She is Frances and has three sisters Marjorie dorothy and Kathleen. Marjorie still lives in Kirbymoorside. Their father was Francis William Ellerker and he was the postman in Kirbymoorside, he died in 1972. He had a sister Elizabeth and their parents were John and Mary Ellerker. John had a brother Christopher and a sister Elizabeth. I think their parents were George and Martha.
