Madoc or Madog ab Owain Gwynedd was, according to folklore, a Welsh prince who sailed to America in 1170. The “Madoc story” remained popular in later centuries, and a later development asserted that Madoc’s voyagers had intermarried with local Native Americans, and that their Welsh-speaking descendants still live somewhere in America. These “Welsh Indians” were credited with the construction of a number of natural and man-made landmarks throughout the American Midwest, and a number of white travellers were inspired to go and look for them.

Who are the Celts?
Celts originated in Central Europe, and left a strong legacy of Celtic culture in Switzerland, Austria and Hungary. Scandinavians, Germans and Slavs generally have evolved from the older Celtic peoples that once dominated part of the Balkans, Spain and northward throughout Europe and parts of northwest Asia.
Celtic Tribes of the British Isles
Before the spread westwards of Angles, Saxons and Vikings, Britain and Ireland were inhabited by people speaking Celtic languages. Who were they? Their origins probably go back to about 2,400 BC, when the first Bell Beaker material appeared in the British Isles.1 Genetically their predominant signature is Y-DNA R1b-L21, which has been found in pre-Roman skeletons in Eastern England.2
Isaelites in America
The name Celts was the designation given to those peoples who emerged from the same geographical location where the so called ‘Lost Tribes of Israel’ had disappeared from at an earlier stage of world history. These people migrated across Europe to settle in the British Isles and the coasts of France and Spain. They were a well organized sea power at the time when Julius Caesar and his Roman legions invaded Britain in 55 B.C.; and he, in fact, makes reference to their ocean-going vessels. Professor Fell has now identified the megalithic structures at Mystery Hill, New Hampshire as a type of temple observatory dedicated to the ancient Celtic sun-god Bel (it was for worshipping this same Baal that their Israelite ancestors had been cast out of Palestine). He claims that other sites dedicated to this same deity and to other Celtic gods and goddesses have been located in Vermont, together with Celtic burial urns and other artifacts.
