Meaning & origin

Jerilyn is a compound name that emerged in the early 1930s, a product of the American fashion for blending masculine and feminine elements. First recorded in 1931, it reached its peak rank in 1942, but has been steadily falling since 1985, reflecting the decline of many 'Lynn' suffixed names. In 2025, Jerilyn ranked 11,932, meaning it is given to only about 1 in 229,610 newborns, making it a distinctive choice. Its usage has never been regionally concentrated, as shown by its absence from top state lists.

Jerilyn is a modern English coinage from the mid-20th century, blending the masculine name Jerry (a pet form of Gerald, derived from Germanic 'spear ruler') with the feminine name Lynn (from Welsh 'llyn' meaning 'lake' or a variant of Linda). It first appeared in U.S. records in 1931 and peaked in popularity in 1942, reflecting the trend of compound '-lyn' names for girls.
