Reginald

Reginald is a boy's and girl's baby name of Germanic origin, a Latinized form of Reynold, from the Old High German Raginald — combining ragin ('advice,' 'counsel') and wald ('ruler'), meaning 'wise ruler' or 'counsel-power.' The Normans brought it to England as Reynaud, which Latinized to Reginaldus.

Reginald peaked in the U.S. top 100 around 1920–1940 and has been particularly beloved in African-American naming traditions. The nickname Reggie gives it an athletic, approachable shorthand — Reggie Jackson, Reggie White, Reggie Miller all attest to its power.
