Macyn is a contemporary feminine given name that traces its linguistic roots to the Scottish Gaelic patronymic Mackenzie, itself derived from the elements mac (“son”) and Coinneach (“fair” or “handsome”). As a phonetic respelling, Macyn preserves the original cadence—pronounced MAY-sin (/ˈme sɪn/) in English—while adhering to a broader Anglo-American trend of adapting traditional surnames into first names with novel orthography. From a quantitative perspective, Macyn has maintained a relatively stable niche in the United States, fluctuating within the 800–950 rank range over the past three decades and most recently appearing at number 931 in 2024 with 19 recorded births. This steadiness suggests that, although Macyn has not entered mainstream popularity, it appeals to parents seeking a name that balances historical resonance with contemporary distinctiveness.
