Killiah is in Origin.

Killiah is a rare modern given name, most common in North America, that appears to blend Irish and Hebrew currents. Its opening echoes Irish Cillian/Killian - ultimately from Old Irish cill “church” with the diminutive -ín, often interpreted as “little church,” and sometimes associated with Ceallach, “war/strife.” The -iah ending evokes biblical names and invites comparison to Keilah, a fortified Judean city in the Hebrew Bible, typically glossed “citadel” or “fortress.” As such, Killiah can be read as a contemporary fusion with layered religious and protective overtones.

Usage is recent and sporadic, with the name chosen for its lyrical sound and distinctive twist on Killian or Keilah. Variants and related forms include Killia, Kilia, Keliah, Kyliah, Keelia, Keilah, Killian, and Cillian; nicknames Lia, Liah, Kili, or Kiki. Depending on the preferred root, meanings proposed range from “little church” to “fortress,” or, by association with Keely/Cadhla, “graceful/beautiful.”
