Kesley is of American origin and means "curl-haired". It is often seen as a variant spelling of Casey, which itself evolved from the Irish surname 'O'Casey'. Kesley gained popularity in the United States during the mid-20th century but remains relatively uncommon today.
Kesley's name gained popularity briefly in the late 1970s and mid-1980s, with peaks in 1977 (5 births), 1983 (7 births), and 1986 to 1990 (6 to 9 births annually). However, it seems to have fallen out of favor since then, with only 5 births recorded in 2023. Overall, Kesley was given as a name to 67 babies over the course of these years.
