Hello Sylvia,
Looks like you could be getting pretty close to one on my lines of Cusworths - see my picture, left. It shows Emily Jane Cusworth b. 04/04/1869, Wombwell. (Not far from Wath, in case you're not local).
Her parents were George Cusworth (b. 1827) and Ann (nee Eastwood).
George's parents were William (c. 1790) and Susannah (c.1801). (This is about as far as I've got, though, so far.)
Just to let you know that it seems the Cusworths were quite into big families, and that there could be several cousins around at the same time all called John, George, Joseph etc, so could get a bit tricky sorting one family from another.
My lot lived around the Wombwell, Wath-upon-Dearne, Bolton-upon-Dearne areas. Let me know if I can help in any way (I still live locally and my son goes to a Wath school), and I can get to Rotherham library occasionally if you need anything looking up in Parish Registers.
Feel free to PM me if you want to,

Sally
