Marillyn

Meaning & origin

Marillyn first entered U.S. birth records in 1920, reaching its peak in 1927 before gradually declining. Its trajectory remains stable in the sense that it never achieved widespread popularity, and it has not appeared in recent top rankings. The name reflects the early 20th-century trend of combining Mary, a perennial favorite, with the fashionable -lyn suffix, as seen in names like Evelyn and Carolyn. While Marillyn lacks notable famous bearers, its connection to the more common Marilyn gives it a familiar yet distinctive feel. The name was most common during the 1920s, with no specific top state association due to its infrequent use. As a variant spelling, it offers a subtle twist on a classic, though it has not experienced a revival in recent decades.

Marillyn is a modern English elaboration of Marilyn, itself a popular 20th-century blend of Mary and the suffix -lyn (ultimately from Welsh llyn 'lake' or the diminutive -lin). Mary derives from the Hebrew Miriam, of debated meaning but traditionally associated with 'beloved' or 'bitter.' Marillyn follows the fashion for feminine names ending in -lyn, popularized in the early 1900s. It first appeared in U.S. records in the 1920s, echoing the heyday of Marilyn, which was further popularized by actress Marilyn Monroe (born 1926).
