Kelseyann is of American origin, derived from the Irish name Celsuis which means "frequenting or warlike". It gained popularity during the late 20th century and is often used as a female given name. Kelseyann is composed of two elements: 'Kelsey' and '-ann', where '-ann' is a popular feminine suffix found in many names like Shannon, Reagan, and McKinnon. The name is not typically associated with any specific saint or historical figure, making it a unique choice for parents seeking an uncommon yet appealing name for their child. As of recent data, Kelseyann is not among the top 1000 most popular baby girl names in the United States, suggesting that it remains relatively rare and distinctive. In terms of usage, Kelseyann appears to be more common in English-speaking countries such as the United States and Canada than elsewhere around the world. However, its overall prevalence is limited compared to more mainstream female given names like Emma, Olivia, or Sophia.
"The name Kelseyann saw its first surge in popularity with six births each in 1989 and 1991, followed by a peak of seven births in 1994. Thereafter, it maintained an average of about six births annually until 1996 when there were five."
