Someone molested Jonathan' paternal line. He was born in 1813, and his great grandfather RP was born about 1720, not his father Richard Parsons. So, in my line it goes Jonathan, Richard, John, Richard 1720. Someone made a mess by merging the two Richards ( and probably jumping to a concussion that Jonathan was John, sons of the respective Richards -- taking no notice of the 93 year gap between Jonathan and his "father".
Jonathan Parsons 1813 is my ffmmf via Nancy Parsons Dixon, then Emily Dixon Flowers, who I knew.
