Maddison

Maddison is a modern English given name transferred from the surname Madison, which derived from a medieval diminutive of the name Maud, itself the Norman French form of Matilda, meaning "strength in battle" from Germanic elements. The surname gained widespread recognition through James Madison, the fourth president of the United States, though the name's popular use as a feminine given name was largely sparked by the 1984 film Splash, in which a mermaid adopts the name after seeing a street sign in New York City. It is commonly spelled Madison, with Maddison representing a frequent variant spelling, and the short form Maddie is widely used for both.
