Mary Kinkey, mother of Harmon Husband, had a sister Catherine who married a Cox. I have always presumed that Isaac Cox was probably his cousin. I show nine children from that union but Isaac is not listed as one of them, but that does not mean that one of them was not called by his middle name or that one of the names was written incorrectly. Then again, maybe his uncle had a little brother. Since Harmon was raised by his grandfather Kinkey, he would probably be in close contact with the Coxes.
