Treveon is a modern American spelling variant of Trevon, part of a cluster of similar American names that vary the ending, among them Trevion and Traveon. It has no older documented history in any language; it first appears in US birth records in 1987, which fits that modern American pattern rather than an inherited traditional name. The spelling with -eon is one of several renderings of the same sound.
