Halcyon, deriving from Greek 'halcyona,' meaning kingfisher, is an uncommon yet enchanting given name of Latin origin. It is often associated with the mythical bird Halcyon, said to have nested on water and calmed the seas during its breeding season. Historically, the term 'halcyon days' has been used to denote a period of happiness and calm. Thus, the name Halcyon carries a sense of serenity, tranquility, and beauty.
"Halcyon was a popular name for babies during the early to mid-20th century, with peaks in the 1910s and 1920s. However, its popularity has since waned, with only occasional usage in recent years."
