Likely a combination of May and the suffix -ley
Mayley is a modern American invention, likely created by blending the month name May (derived from the Roman goddess Maia) with the popular 'ley' suffix meaning 'clearing' or 'meadow'. It follows the phonetic trends of names like Hailey and Kaylee. While it lacks a singular ancient root, it carries the cheerful associations of springtime and nature.
