"Mary Fox -- A Possible Daughter?
It is possible Hance Hendrick had a daughter Mary who was the wife of Henry Fox. Unfortunately, though, the evidence is both weak and quite indirect. A widely read Fox family genealogy identifies the wife of one Henry Fox as Mary “Kendrick” based on “tradition in the Kendrick family”.  While there were Fox-Kendrick marriages a couple of generations later, the only supplementary evidence that Fox’s wife was a Kendrick seems to have come from a misreading of a Hanover County record of a 1730 sale of land from Henry Fox to William Hendrick, both of King William County. 
There is no direct evidence that Henry Fox’s wife was either a Hendrick or a Kendrick. She could as easily have been a Smith or a Jones. What we can say for certain is that she was far more likely to have been a Hendrick than a Kendrick. For one thing, there is no mention at all of anyone named Kendrick in the admittedly sparse King William records. But we can reasonably conclude that Henry Fox was well acquainted with Hance Hendrick. Hance Hendrick and Henry Fox were among the 89 residents of King & Queen who petitioned for the formation of King William County in 1700.  Henry Fox, in fact, had a patent located less than two miles from Hance Hendrick’s land."
