Modern invention, likely combining Keon and the suffix -tre
Keontre is a modern American name, likely created as a rhythmic blend of Keon and the suffix -tre. Keon itself is often considered a variant of the Irish name John (meaning 'God is gracious') or the Persian name Kian (meaning 'king' or 'ancient'). The suffix '-tre' is frequently used in African American naming traditions to denote 'the third' or simply to add a melodic flair.
