findagrave lists a Catherine as a third wife. The findagrave for his son Leonnie lists a different Catherine as his mother. I have found little to document any Catherine as a wife of Frederick, nor a Leonnie as a son. The stone for the Catherine linked on Frederick's page does mention her as a wife of a Worden, but I cannot make out the first name.
