According to folklore, Madoc was a Welsh prince who sailed to America in 1170, over three hundred years before Christopher Columbus's voyage in 1492. While most historians dismiss the legends, some scholars claim that Madoc's voyagers had made it to the New World, intermarried with local Native Americans, and that their Welsh-speaking descendants still live somewhere in the United States.

There was a time that pre-Colombian Viking voyages were also dismissed by academia, until evidence of Viking settlements in the Americas proved the Icelandic legends to be true. That said, these alleged Welsh Indians have been credited by some to have constructed a number of landmarks throughout the Midwestern United States.
