Marriage Reg,
Dec 1839, Settle, 23 547
James BATES and Mary Ann JOHNSON on same page
From Familysearch.Org;
Mariage 28 October 1839, Clapham, Yorkshire
James Bates to Mary Ann Johnson
Now I think the M/C is a must if you want to go back any further with Benjamin.
As for Mary Ann, possible;
MARY ANN Johnson Christened 11 May 1820, Greystoke, Cumberland
Parents RALPH/ANN
Siblings;
ELEANOR, 18 May 1811
JANE, 10 March 1813, Buried 20 Jan 1820
JOHN, 14 March 1818
JUDITH, 29 June 1823
Eleanors has Mothers name as Ann TODD, which leads to this Child Christened Skelton to Ralph/Ann Johnson/e nee Todd;
GEORGE, 22 March 1808
Marriage;
8 June 1807, Greystoke, Ralph JOHNSTONE to Ann TODD
The reason I chose this one is that keyboard86 found a 1841 Census for James/Mary Waterfall in Cheshire.
1841 Census has a JUDITH Johnson, Servant, age 20, living in Stockport, Cheshire.
She is not born in County.
Also John Johnson 1818 Greystoke is Widowed and living in Durham in 1851. His Children are born Northumberland.
Worth noting if M/C has Mary Ann Father as Ralph
