Meaning & origin
Mattilyn entered the U.S. naming scene in 1994, a product of the modern trend for blending traditional name elements with the ever-popular -lyn suffix. Its peak year came in 2012, when it reached its highest rank, but it has been steadily declining since 2013, reflecting a shift away from this style. With an incidence of 1 in 107,151 newborns in 2025, it remains a rare choice. Although it never cracked the top 1,000, its trajectory demonstrates how niche coinages can emerge and fade within a generation, embodying a distinctly American approach to name creation.
Mattilyn is a modern invented name, likely formed from the root Mattie (a diminutive of Matthew, meaning 'gift of God' in Hebrew) combined with the fashionable suffix -lyn, popularized by names like Evelyn and Marilyn. It first appeared in U.S. birth records in 1994 and saw a peak in 2012, reflecting a trend of creating feminine names with familiar components.
