Calhan is a distinctive and strong name of Irish origin, typically given to boys. It is pronounced as KAHL-han (/kɑːl hæn/) in English. The name Calhan is derived from the Gaelic surname "Ó Ceallacháin," which means "descendant of Ceallachán." Ceallachán itself is rooted in the word "ceallach," meaning "strife" or "war." This gives the name a historical and robust connotation, making it appealing for parents seeking a unique yet powerful name for their child. A notable variation of the name is Calhoun, which shares similar roots and pronunciation. Despite its rich heritage, Calhan remains relatively rare in the United States, with only 11 occurrences in 2022, ranking it at 7251 for that year. Its rarity adds to its charm, offering a distinct choice for those looking to bestow an uncommon yet meaningful name on their son.
