What is the meaning of the name Keryll ?

Keryll is English, Welsh in Origin.

Rare in modern use, Keryll is a flexible, largely English-language spelling that can follow two main etymological paths. One links it to Irish Kerrill, an Anglicized form of Old Irish Caireall/Cairell borne by an early medieval saint honored in east Galway; the original meaning is disputed and possibly pre-Gaelic, sometimes glossed “warrior,” though scholars mark it as uncertain. Alternatively, Keryll is treated as a creative variant aligned with Cyril/Cheryl: from Greek Kyrillos “lordly” via Cyril, or from the Carol/Charles family meaning “free man,” filtered through mid‑20th‑century Cheryl.

Usage is very rare, with spikes where Irish heritage or mid‑century K‑initial fashions encouraged respellings. The form appears for both sexes - more often feminine when tied to Cheryl, masculine when tied to Kerrill/Cyril. Variants and relatives include Kerrill, Kerill, Keryl, Karyl, Caryl, Ceryl, Cheryl, Kerry, Kerryl, Cyril, Kirill. Meanings follow the chosen lineage: uncertain (Irish), “lordly” (Greek), or “free man” (Germanic).
