From what I understand, there were 5 brothers, not substantiated yet, who came over to America. William, Richard, John and another 2 brothers. They were sons of a planter, Thomas,,also not substantiated. If Thomas owned plantations in Jamaica as indicated, they would probably have been backed monetarily by their father. None of this has been documented though. But it does lend itself to the brothers being educated and from a fairly well to do family. I just wish I were able to find some links between John, Richard and William to Thomas the planter in Jamaica. The Jamaican plantation owners at the time were very wealthy and respected in England. This may give another avenue of research. Let me know your thoughts on this.
You can email me directly to WNDJ48@aol.com if you wish. My brother in law, Robin Kash and Reis Kash, distant cousin are also actively researching this. My eldest daughter, Heather, is also looking.
