Ashlye is of American origin, derived from Ashley which means 'from the ash tree meadow'. It gained popularity as a feminine variant of Ashley during the mid-20th century. Ashlye is often spelled with an 'y' to distinguish it from Ashley. In terms of popularity, Ashlye has not been among the top 1000 names for girls in the United States since the 1990s, suggesting that it may be considered somewhat unique or less common today.
Ashlye saw its peak popularity in the late 80s to early 90s, with 21 births recorded in 1988 and consistently high numbers until 1994. After that, it began a steady decline, with only a handful of births per year from 1995 onwards. The name's popularity has not regained momentum since its peak nearly three decades ago.
