Hi there. Bishop and Phebe Holloway were my ancestors as well. Judging by your last name, you must be a descendent of Flavia Cornell. My great-great-great... Grandfather was Albert Holloway, Flavia's brother.
Through some brief research, I found out that Bishop was born or resided in Maryland. He and his wife resided in Anderson, Indiana briefly in or around 1833-1835.That might help your search. Would love to know if your research has led you further back!
