Great-great-great-grandfather John Stone

My great-great-great-grandfather John Stone was born in 1738 and died in 1814. He had two wives, a total of twenty-five children (or maybe more), and at his death left sixteen heirs. His youngest son, Jacob Porter Stone, was my great-great-grandfather. I started tracing all the descendants of John Stone close to 35 years ago. It's been fascinating, and at this point I see no end to it. In the process I've found many distant cousins, shared much information, and became totally involved in the research.
