I can't connect the pieces. Isaac, James, and John Newhouse all served in the Washington County (VA) militia around 1800. Just across the state line we find Benjamin Green in what was then Hawkins County (TN). He was there from at least 1786 to 1800. Green family lore says Benjamin's wife was Mary Newhouse. Benjamin moved to Henry County (KY) in 1801. A Joseph Newhouse, wife named Joanna, died there the same year. However Rice family lore says Benjamin Green married Mary Rice daughter of John Rice. The will of John Rice (1812) however mentions 'William son of my first wife Elizabeth' which sounds as if William might have been a stepson (he was left one dollar). Could John Rice's first wife, Elizabeth, have been the widow of a Newhouse?
