Hello, I am wondering if anyone has any information on the parents of my great grandparents, Robert and Mary Heron from West Hartlepool. They were both born around the turn of the 20th Century and both died close together in the late 1970's shortly followed by their son (my grandfather) Leslie Heron. They were both staunch Methodists but later joined the Salvation Army. Any information would be appreciated. Thankyou.
