Hello
I have had a look at several of the census and John and Mary with the three children gave their place of birth as
Essington, Staffs for John and Shareshill, Staffs for Mary.
These places were/are in Wolverhampton district.
If this is the case I found a John Bentons (coal miner) marriage to Mary
Ward 25 Dec 1840 Wolverhampton. Father Samuel
Benton.
Good
