I to am a Born descendent from John Born. Also from Jacob Born and Jemima Morgan via Caroline Born Ragsdale. I have a copy of an old book, 'The genealogy of the McElvany-Born Families. 1932" by Carlie Kemp. It follows the descendents of Jacob Born for 5 or 6 generations (not in great detail and it has many holes) It does cover your line to John J. Born m. Eva.
