Rooted in Greek, Gaelen is a modern respelling of Galen, from Galenos via Latin Galenus, meaning “calm” or “serene.” The name became known in the West through Galen of Pergamon, the influential 2nd‑century physician whose works shaped medical learning for centuries. Through scholarly and humanist circles, Galen entered English naming in the Renaissance, saw intermittent use in Britain and America, and experienced modest revival in the 19th–20th centuries.

Gaelen reflects contemporary taste for the ae spelling and the visual pull of Gaelic‑looking names, yet its meaning remains “calm/peaceful,” with a cultural association of “healer” thanks to the famed doctor. Variants and related spellings include Galen, Gaylen, Gaylon, Gaelan, and Gaelin; Galen/Gaelen function as unisex in modern use. Note that Gaelen is often confused with Caelan/Keelan and Gael, which are Irish in origin (from Caolán, “slender”) and etymologically distinct.
