Meigs lists eight children for our subject, the four given by Hardy, plus four more.  The booklet is entirely lacking documentation, so it's reliability is uncertain.  I will say that he has the good judgment to doubt the connection to John CORBIN of Richmond (the Northern Neck CORBINS) and to doubt the one to the CORBINs of the eastern shore (the Delmarva CORBINs), both of whom Y-DNA evidence has shown are not related either to Henry or to each other.
