1599-1790. I have no brother for my Richard Bush who was from Fairfield, NJ and born in Passaic 7 Feb 1756. It seems that our Bush family hailed from Denmark originally. So perhaps you have an English Bush that settled in the southern states.It would be helpful to know their religion. If they were Catholic they would have gone to Maryland, If Anglican, Virginia and Carolinas... etc. Dutch or Hugeunots or Walloons settled in Upper New York state along the Hudson, New Amsterdam ( NY) and New Jersey after 1695.
I know most of the Bush family from New York and New Jersey if that is helpful.
