Kyllians

Kyllians is a less common variant of the name Killian, which itself is an anglicized form of the Irish Gaelic name Cillian. Cillian is derived from the Old Irish word 'cill', meaning 'church' or 'cell', often referring to a monastic cell. It can also be associated with 'ceallach', meaning 'war' or 'strife', thus giving it a secondary meaning of 'little warrior' or 'bright-headed'. The name has a long history in Ireland, particularly due to Saint Cillian, an Irish missionary who evangelized in Germany in the 7th century.

The spelling 'Kyllians' adds an 's' at the end, which is not typical for a singular given name in Irish tradition and might suggest a patronymic influence (son of Kyllian) or a modern, perhaps Americanized, stylistic choice. It retains the core etymology and historical roots of Cillian but presents a unique, albeit less traditional, form.
