Jerelyn is an English feminine given name of modern coinage, likely emerging in the United States during the early twentieth century as an inventive fusion of Geraldine—itself derived from the Old German elements geri “spear” and lind “soft”—and the popular suffix -lyn found in names such as Carolyn and Evelyn. Its standardized pronunciation in English, rendered as JER-uh-lin (/ˈdʒər.ɪl.ɪn/), remains uniform across both British and American variants, reflecting an unwavering Anglo-American phonetic profile. A longitudinal analysis of Social Security Administration records indicates its inaugural appearance circa 1924, followed by sporadic but measurable usage throughout the mid-century decades, modest peaks in the late 1980s (attaining rank 807 in 1988), and a gradual decline to five recorded births and rank 945 in 2024. Connoting a blend of poised resilience and understated elegance, Jerelyn appeals to those seeking a name that balances historical resonance with contemporary subtlety.
