Hello Christine -
That is interesting, so John was Stephen's older brother, and was presumably also born at Wharton. As I'm sure you'll know, George & Elizabeth married in 1830, but I think Elizabeth died not very long after Stephen's birth in 1840.
Several of Elizabeth Chesters's relations farmed too, some near Holmes Chapel, though around Winsford seems to be the family patch. In fact, the first Stephen CT's in-laws, the Fairhursts (hence Charlotte's second name) were farmers / smallholders near Northwich too.
You'll see from the marriage certificate that the Stephen CT's older child, Charlotte, married Patrick Casey Connolly in Leek R.C. Church while her father (then remarried to Caroline) lived at a house nearby on Rudyard Lake - of which there's rather a lot I could tell you.
Once married they they moved (and I expect this is why you can't trace her) to a Drogheda Hall / House (?) in Ireland. I was led to believe (and I don't think one can libel the dead!) he was a drunk and things were not a great success. Other than that I'm afraid I don't know a great deal about her, save that she survived some appalling hunting accident when she fell on spiced railings.
However, she eventually returned to Cheshire / Manchester without her husband, who may have been dead by then. She probably died in the 1930s / 40s. She had no children but my grandparents occasionally mentioned "Lotty's pots" - which I think were some sort of ornament, rather than an insinuation that she was mad. Anyway, I don't believe I ever saw the said pots, though I think my parents have one of her Irish paintings.
Best wishes, Simon
