Kaylle is a unique and distinctive given name of Hebrew origin. It is derived from the Hebrew word "kayil," which means "strength" or "power." The name Kaylle is believed to have been popularized by American author Anne Rice, who used it as the first name of one of her characters in the "Lives of the Mayfair Witches" series. Despite its Hebrew roots, Kaylle has gained popularity worldwide and is often seen as a unisex name, although it is more commonly given to girls. Its meaning and strong connotation make it an appealing choice for parents looking for a powerful and distinctive name for their child.
Based on U.S. birth records, the name Kaylle has had limited popularity over time. In fact, there was only one year when the name gained any notable traction: 1984. That year saw a total of five babies being named Kaylle in the United States. This is by far the peak year for the name, as no other years have come close to matching this number. From 1985 onwards, the name has not been included among the Social Security Administration's list of popular baby names in the U.S., suggesting that it may be considered quite uncommon or unique today.
