There seems to be circumstantial evidence to show Samuel Bigby to be the father of James Bigby, Sr., as explained in a previous posting by Jerry Clark. If there is written definite proof of his fraternal parentage apparently that has not been discovered at this time.
The listing of the 97% or so of the Cherokee people who signed a petition protesting the "removal" of the Cherokee Nation to west of the Mississippi River in the 1830's was signed with the names of James Bigby, his wife Catherine (Foreman) Bigby, their children and spouses, and many Foremans. Most of them, of course, were forced by U. S. government representatives to move west.
The Cherokee Nation currently has a hallway exhibit in the main office building at Tahlequah, OK showing a copy of the petition with the complete listing of names, many written in Cherokee and some in English. Along with the petition are large photographs of scenes showing the location of stockades where the people were pinned up for months before the trip, and sites along the routes of travel. Also exhibited are snapshots taken of young Cherokee people who recently rode bikes along one of the routes.
