Lettie-Lou is English in Origin.

Blending two affectionate diminutives, Lettie-Lou fuses Lettie - pet form of Letitia/Leticia/Lettice, from Latin laetitia “joy, gladness” - with Lou, the familiar short form of Louise/Louisa (ultimately from Germanic Ludwig: hlud “famous” + wig “war”). Together the name suggests “joyful famed warrior” or more softly “joy and renown.” Hyphenated double names have long roots in Anglo-American naming, with particular warmth in the U.S. South and periodic revivals in Britain.

Usage traces to the 19th century, when Lettie thrived as a stand-alone Victorian nickname and Lou commonly followed given names as a cozy second element. Contemporary parents favor Lettie-Lou for its retro-lilt and approachable charm. Variants include Letty-Lou, Lettie Lou, LettieLou, and Letty Lou; related forms are Lettie, Letty, Lou, Lulu, and Lottie-Lou.
