Likely a modern spelling of Maisie or a playful surname-style coinage, used mainly for its bright contemporary sound.
Mazey is a sunlit, informal variant of Maisie, itself a Scottish diminutive of Margaret. That ancient name traces back through Old French Marguerite to the Latin Margarita and ultimately to the Greek margaritēs, meaning "pearl." By the time Maisie emerged in the Scottish Highlands, the pearl imagery had been replaced by something more homespun and affectionate — a pet name that felt like a warm hand on the shoulder rather than a jewel in a crown.
Mazey takes that softness one step further, swapping the -ie ending for a -y that feels breezy and modern. Maisie has a distinguished literary champion in Henry James, whose 1897 novel What Maisie Knew placed the name at the center of a sophisticated psychological study of childhood and adult corruption. The name also belongs to Maisie Ward, the influential 20th-century Catholic intellectual and biographer.
These associations give the Mazey/Maisie family an unexpected literary pedigree beneath its cheerful exterior. Mazey in particular occupies the contemporary naming moment very comfortably — it sits alongside Daisy, Lacey, and Poppy in a cohort of names that feel vintage without being fusty, feminine without being elaborate. Its double-z spelling (compared to the single-i of Maisie) gives it a slight visual spark, suggesting energy and individuality while keeping the name's essential warmth entirely intact.
