AQHA gives breeding as unknown. They did not transfer the info from the old Appendix into the computerized database. Correcting error found on Charlotte Dart. Lil sis was another of my Grandfathers nicknames for his horse. She was not registered and Lil Sis was a nickname he gave to Dart. Found notation in his journal with Charlotte Darts line. Neither one is registered and the Seabiscuit he has as the father was raced in New York in 1935 so therefore I don't thinks it's THE Seabiscuit. Sorry for wrong advice but very sure this is the true information on Charlotte Dart.
