Caoilfhionn is Irish in Origin.

Caoilfhionn is an Irish Gaelic feminine given name from Old Irish elements caol “slender” and fionn “fair, bright,” yielding the sense “slender and fair(-haired).” In Irish, lenited fh is silent, so it’s usually pronounced KEE-lin, with KWEE-lin or KAY-lin also heard.

The name appears in medieval annals and bardic verse among learned and noble families; after decline under Anglicization, it revived in the Gaelic Revival and today sees modest use in Ireland and the diaspora. Anglicized or phonetic forms include Keelin (most common) and Keelyn; Kailin/Kaylin occur but are independent in origin. Related names from caol include the masculine Caolán, distinct from Caoilfhionn. Though firmly feminine in Irish tradition, Keelin is the usual Anglicized feminine form. Do not confuse it with Cailín (“girl”), Caoimhe, or the masculine Keelan (from Caolán), which are unrelated.
