Maddisyn is of American origin, derived from the name Madison, which itself has English roots. It means "son of Matthew," a popular biblical figure whose name signifies gift of God. Maddisyn gained popularity in the late 20th and early 21st centuries, likely influenced by the rising trend of names ending with "-syn" among American parents. It is often used as a feminine variant of Madison but can also be considered a standalone name. Spelling variations include Maddisen, Madisin, and Maddsyn.
"Maddisyn's popularity peaked around 2007 to 2009 with over 50 births per year, but it has since declined, averaging around 30-40 births annually from 2010 onwards."
