John B MILLS, son of James MILLS - Bethany GUSTIN and 2nd wife of James was Bethana GUSTIN FRENCH of Warren Co OH ca 1800 to 1830.
John moved on apparently to Indiana. married Celia NATION, descendant, at least by what is posted "out there" on the net, of William St CLAIR of Rosslyn Chapel, Scotland, per his grave stone shown in the PBS special named "Angels and Demons" shown a couple months back on channel 10 here in Portland, Oregon. Not sure if stone was placed there for the movie of the same name, or ? Just to add a bit of trivia to the group.
