Sevyn broke into the Top 1000 for girls in 2019, the same year that Seven crossed the threshold for boys. Ys are typically employed to make names more feminine, which is why many more girls were given the Sevyn spelling than boys. However, Sevyn still made it on the birth certificates of over 100 boys last year.

2019 was the year of seven, as both Seven (for boys) and Sevyn (for girls) broke into the Top 1000. Sevyn's use may be inspired by Sevyn Streeter, a singer and songwriter. She was born Amber Denise Streeter but chose Sevyn as her stage name — rather appropriately, since her birthday is July 7.
