Frank: There is a web page that shows Louise Prosser Bates was Louise Snow Prosser married to F. E. Bates (it does not show his ancestry). Louise Snow Prosser was shown to be descendant of John Kenyon Prosser and Mary Wilbur and , in the previous generation, John Prosser and Ruth Larking (born ca 1773) in Richmond RI. Of course, I cannot verify these data just indicate that "it is out there." Jean
