I agree that Agnes was certainly the wife of Benjamin II. I was merely asking whether Denise was familiar with Herbert's book and outlining his research for her.
However, since you brought it up, is the Gragg genealogy you mentioned available on line? I have always questioned who's wife Margaret was. I had thought that perhaps she was a first wife of Benjamin II, but if there is evidence that she was born in the 1720s, then she was probably the wife of Benjamin I.
Secondly, do you know of any evidence (other than family tradition) that Agnes' maiden name was Lane? I don't know of any, but would love to see it.
