Hello Cousin Marilyn. Yes, I do believe the Peter Jones and the Cadwallader Jones families are related. Much had been written about both of these families. The classic is: Peter Jones and Richard Jones Genealogies, by Augusta Fothergill, Old Dominion Press, Inc, Richmond, VA, 1924. If you have not seen a copy of this, you should try and locate one, since it is the foundational work on this family group. An additional reference is: A Genealogical History, By Colonel Cadwallader Jones, published 1899. Both references are muddy about the early immigration period, and leave many unanswered questions. I have spent many years researching these families. To date my research suggest that they originate from the ancient Cornovii tribal groups which occupied the strategic, geographic land entrance to what was to become Wales. They occupied the land between the headwaters of the River Dee to the North, and the headwaters of the River Severn to the South. Thus they controlled the only "land" access to the bread basket of Wales. This became a key land bridge for the trade between the tribal groups, and a key "military zone". The ancient trade routes were constantly contested and Iron age hill-forts dot the landscape. A hotly contested battle occurred here 5 August 642 AD, and a Christian King of Northumberland was slain by a Pagan King of Merica. (This Pagan King was recruited by the King of NW Wales to fight!) Legend has it that the Christian King was defeated, and to mock "Christianity", the Pagan King had his defeated foe's body parts attacked to several crosses. The Welsh came to call the place Croes Oswald. This to others became Oswestry. This area seems to be center of our family group. As you can tell, there is much more to this family story. Copies of the references quoted above are located at the Joseph Wheeler Jones Memorial Library, Danville, KY. My personal research notebooks are also available to the JONES researcher by appointment.
