Trevlyn is English in Origin.

Trevlyn (TREV-lin) is a modern Cornish-derived given name formed from a long-established surname family: Trevelyan/Trevillian. These surnames descend from Cornish place-names built on tre, meaning “homestead, settlement,” combined with the personal name Elyan (a Cornish form of Julian). The core sense is “Elyan’s homestead” or “Julian’s settlement,” with Trevlyn representing a streamlined, contemporary spelling while preserving the tre- heritage common to many Cornish names.

Found as a surname in medieval Cornwall and familiar to readers through 19th‑century literature (e.g., Mrs. Henry Wood’s The Trevlyn Hold), Trevlyn began occasional use as a first name in the late 20th century across English-speaking countries. Variants and related forms include Trevelyan, Trevelian, Trevillian/Trevillion, Trevlin, and Trevlynn; short forms include Trev and Lyn. Unisex in modern practice but more often masculine, it carries a rugged, place‑name charm with Celtic roots.
