Meaning: Shannyn is a stylized spelling of Shannon, the name of Ireland's longest river, from the Irish 'Sionainn', linked to a goddess and to a sense of 'old' or 'wise one'. Replacing the vowels with a 'y' pair gave the unisex Irish name a more distinctly feminine, modern look.Low

History & Origin
Shannyn is a decorative spelling of Shannon, taken from the River Shannon, the longest river in Ireland, whose Irish name Sionainn is tied to a goddess and read as 'old' or 'wise'. Once used for both sexes, Shannon leaned female in America, and the 'yn' spelling emphasized that feminine, fashion-forward feel.
Shannyn was always scarce, peaking around 2002 at about thirty girls a year and appearing thinly into the 2010s. It belongs to the era's habit of respelling familiar names with 'y'; a Shannyn from the peak would be in her twenties, and the spelling stays a genuine rarity.
