Lethiah is in Origin.

Lethiah is an uncommon feminine name from English-speaking usage, most plausibly a late-19th‑century variant of Lethia/Letha. Those forms developed as shortened or respelled versions of Alethea, the Greek-derived virtue name meaning “truth” (from aletheia), and they were also shaped by the phonetic pull of Letitia/Leticia, from Latin laetitia “joy.”

Records place Lethiah and its close forms in American church books and censuses from the 1880s into the early 20th century, with sporadic revival today among parents seeking antique rarities. Spelling variants and related names include Lethia, Letha, Alethia, Alethea, Aletha, and Letitia/Leticia; nicknames range from Letty to Thea. The terminal -h in Lethiah reflects period spelling habits and lends a biblical-leaning silhouette without altering pronunciation. Depending on the line of derivation chosen, the name may be read to mean either “truth” or “gladness, joy.”
