Combination of Tre and Lyn
Trelyn is a modern American invention, likely created by blending the prefix 'Tre' (often meaning three or derived from Trevor) with the suffix 'lyn'. While 'Tre' has roots in Cornish and Welsh meaning 'homestead', this specific combination is a contemporary coinage without a singular historical lineage.
