Meaning: son of Adam

Addison became a trendy girl's name soon after the introduction of a major character, Dr. Addison Montgomery, on Grey's Anatomy in 2005. Since the love affair with Addison shows no signs of waning, parents who like the name but not its mega-popularity are giving it a slight spelling twist to make it a bit different. That's how Addyson, which means "son of Adam," was born. While Addison might be more popular as a girl's name, Addyson is perfect as a gender-neutral name for baby. This name has British origins and lends itself to the sweet nickname Addy.
