Meaning & origin
Tamilyn is a modern American coinage that first appeared in U.S. birth records in 1958, part of the mid-century fashion for names ending in -lyn (like Jocelyn and Alyssa). Its peak year was 1969, reflecting the era's taste for feminine, blended names. Although it has never been extremely common, its trajectory is stable and it remains a distinctive choice. Tamilyn is primarily a girl's name.
Tamilyn is a modern coinage, likely formed by combining the nickname Tammy (itself a diminutive of Tamara or Thomasina) with the popular suffix -lyn, a variant of Lynn. It first appeared in U.S. records in 1958 during the mid-20th century trend of creating feminine names with the -lyn ending. The name saw modest use in the 1960s, peaking in 1969, and has since become rare.
