Kelsey

This baby name has suffered from overexposure: During the last decade or two of the 20th century, there were a whole lot of Kelseys on the playground and in school, and they were almost all girls. (Shout-out to early male namesake pioneer, Kelsey Grammer of “Frasier.”) Though its rapid ascension up the popularity charts has slowed down, Kelsey will likely be sticking around for a long time, so you’ll never have to worry about it sounding dated. Baby names beginning with K will always be in demand—just ask Kim, Kourtney, Khloe, Kylie and Kendall.
