We're All Related to Charlemagne

But some people (like the Vigils) have better proof:

According to Henrietta Christmas, president of the New Mexico Genealogical Society, people in New Mexico who have the surname Vigil most likely have a common ancestor who is a descendant of Charlemagne.

...Thank Juan Montes Vigil, the common ancestor and descendant of Charlemagne, for the New Mexico connection, but thank Colorado-based researcher Brent Alexander Cruz for finding the link between the Montes Vigil ancestry and the prominent Ponce de León family descended from Alfonso IX (1171-1230), King of León, who was a descendant of Charlemagne. Cruz’ research looked at documents dating from the 700s to the 1300s.

Juan Montes Vigil was a native of Vega de Poxa, in the region of Asturias in northern Spain. In 1611, he traveled to Mexico City and married Catalina de Herrera Cantillana. They had a son, also named Juan Montes Vigil, who later settled in Zacatecas, Mexico. He, in turn, fathered a son named Francisco Montes Vigil.

In 1665, Francisco traveled north into what is now New Mexico as a settler, along with his wife, María Jiménez de Anciso, and their five children. Francisco and María established the Vigil family of New Mexico, Esquibel said.
