Lonnie

Lonnie is a boy's and girl's baby name of uncertain origin, used primarily as an informal given name in American English, often considered a pet form of Alonzo — the Spanish variant of Alfonso, from the Germanic elements meaning 'noble' and 'ready' or 'battle-prepared.'

Lonnie was particularly popular in the American South and Midwest through the mid-20th century, carrying an easygoing, informal warmth. Blues musician Lonnie Johnson — a guitarist who influenced both jazz and rock — gave the name a musical legacy. It has the kind of unpretentious, good-natured feel that wears well in any era.
