 Other scholars have pointed out that Charlemagne's mother, Bertrada of Laon, came to be known as the goose-foot queen ("regina pede aucae").There are even sources that trace Mother Goose's origin back to the biblical Queen of Sheba.Despite evidence to the contrary, it has been stated in the United States that the original Mother Goose was the Bostonian wife of Isaac Goose, either named Elizabeth Foster Goose (1665–1758) or Mary Goose (d. 1690, age 42).
