Slender or small; possibly a variant of Keelan
Keelon is most likely a modern phonetic variant of the Irish name Keelan, derived from 'CaelΓ‘n'. It stems from the Gaelic word 'caol', which translates to slender, narrow, or fine. While rare in this specific spelling, it follows the trend of two-syllable Irish-inspired names ending in 'n'.
