Looking for John Hindmarsh B 1800 IN Northumberland

Hi,
I am looking for any information about a John HINDMARSH b.1800 in Northumberland. He is my gr-gr-grandfather who married Mary Jobling. I have no details about Mary but they had 11 children including my gr-grandfather, Edward Hindmarsh.

I think John's father and mother were called Ralph Hindmarsh and Sarah Scott but I have no proof of this as yet.

Edward Hindmarsh was born on 26 July 1838 at Killingworth, the son of John, a Pitman and Mary Hindmarsh, nee Jobling. The informant of the birth was the baby's mother Mary, resident at Killingworth Colliery. She signed with a cross.
