Madisyn

From an English surname meaning "son of MAUD". It was not commonly used as a feminine name until after the movie 'Splash' (1984), in which the main character adopted it as her name after seeing a street sign for Madison Avenue in New York City. A famous bearer of the surname was James Madison (1751-1836), one of the authors of the American constitution who later served as president.

Usual medieval form of MATILDA. Though it became rare after the 14th century, it was revived and once more grew popular in the 19th century, perhaps due to Alfred Lord Tennyson's poem 'Maud' (1855).

From the Germanic name Mahthildis meaning "strength in battle", from the elements maht "might, strength" and hild "battle". Saint Matilda was the wife of the 10th-century German king Henry I the Fowler. The name was common in many branches of European royalty in the Middle Ages. It was brought to England by the Normans, being borne by the wife of William the Conqueror himself. Another notable royal by this name was a 12th-century daughter of Henry I of England, known as the Empress Matilda because of her first marriage to the Holy Roman Emperor Henry V. She later invaded England, laying the foundations for the reign of her son Henry II.

The name was popular until the 15th century in England, usually in the vernacular form Maud. Both forms were revived by the 19th century. This name appears in the popular Australian folk song 'Waltzing Matilda', written in 1895.
