Kienon is in Origin.

Kienon is a modern English given name, most likely a phonetic variant of the Irish surname-given-name Keenan, itself from Ó Cianáin (“descendant of Cianán”). Cianán is a diminutive of Cian, ‘ancient, enduring,’ so the name carries senses like ‘little ancient one’ or ‘of longstanding strength.’ The Kie- spelling reflects contemporary American style and aligns it with names like Kieran and Kian. Rare in historical records, Kienon appears in late-20th-century naming data and remains uncommon.

Parents considering Kienon might also encounter variants and cognates: Keenan, Kienan, Keanon, Keion; and the related Irish Kieran/Kieron (from Ciarán, ‘little dark-haired one’). Because of these intertwined roots, some read Kienon as blending the Keenan and Kieron streams. Use has been sporadic across English-speaking countries, with far greater prevalence for the older forms. Meaning is typically taken from the Keenan/Cianán line: ‘little ancient one,’ extending to themes of endurance and tradition.
