I may be looking for the same info. Barnabas Cain had a sister named Margaret. Barnabas was born in 1770. He married Elizabeth Quaggim in 1790. There father was Thomas Cain and his father was William Cain. I have info that William died in 1777. His will mentions both Thomas and Barnabas and Barnabas's sister Margaret. I would love any info that you may have that can answer some of my questions.
