Hi Scott,
I spent some time digging around yesterday unfortunately not with much luck

If I may ask you, how did you get the ages for John & Sarah, from the removal order?
IGI has only recorded baptism's for Sarah 26/6/1818 at Dorking & Benjamin 1/10/1820, Abinger. No evidence of the twins you talk about, William & Mary 1822.
I found two likely marriages for John & Sarah;
1. John Stedman to Sarah Longhurst 17/10/1810, Ewhurst
2. ditto to Sarah Chandler 7/6/1817, Capel. I checked on the pr transcipt I have & this Sarah was a widow.
Now, in 1851 at Abinger ( HO 107/1598/29/15) I found a John Stedman, ag lab, age 69, born Abinger, lodging with;
John LONGHURST 36 ag lab b. Abinger
Hannah 34 b. Ockley
Harriet 19 b. Abinger
David? 10 ditto
Jane? 5 ditto
George 3 ditto
It's not clear on the image if this John Stedman is unmarried or widowed, my guess says it's unmarried but that could be a mis-understanding when they gave the information.
It looks like this Sarah LONGHURST (who married John Stedman in 1810) was baptised 19/5/1787, Ewhurst d/o Walter & Mary.
This John Stedman (in the 1851 census) was baptised 5/8/1814, Abinger s/o William & Sarah.
The connections with Longhurst, Abinger & Ewhurst all seem to point in the right direction.
We have a LONGHURST researcher on the board, Dawn our moderator so she might be able to add some more to this.
