I beleve that John Lipps who married Rebecca Harden may be the connection you are seeking. Their son John Lipps married Eva "Nancy" Hedrick. John and Eva had Elizabeth Koontz Lipps born 1/2/1810. She was the cause of her son having Raven Black hair and that line of Fleshmen decendents haveing brown eyes (all the rest had blue eyes).
John the son, "was an Indian with hair so black that it looked blue. Was tall, and looked like a Greek God."
-also- Father had blue-black hair. Was a "Kooa" Indian and looked like a Greek god.
They were into horse racing and breading. The hourse racing was done in Washington DC and was the single style. (single style meaning is unknowen)
