Alexis, a one-time exclusively-boys' name, was more popular than its sister Alexandra for quite a while, but last year Alexandra was the more popular name. Alexis was a top 20 girls name from 1994-2010 but has experienced a sharp decline in popularity in recent years. It dropped from 16 in 2010 to 86 in 2015, and dropped out of the top 100 for the first time since 1987 last year, to 119.
Alexis zoomed to popularity following the introduction of the Dynasty character Alexis Carrington in the 1980s--which gave it a sexy, sleek image--was quite popular throughout the 90's and 2000's, peaking at the third most popular girls name in 1999.
One of the few notable female pre-Carrington Alexises was 1940s actress Alexis Smith, who had some minimal impact on the name, which entered the list in 1943. A current bearer is Alexis Bledel, who played Rory on Gilmore Girls.
