Lettie-Jo is English in Origin.

Lettie-Jo is a double-barreled diminutive that fuses Lettie - most often a pet form of Letitia or Lettice, from Latin Laetitia “joy, gladness” (sometimes linked to Colette) - with Jo, the clipped form of Josephine (Hebrew Yosef “he will add”) or Joanna/Joanne (Hebrew via Greek “God is gracious”). Together, the name carries a warm layered meaning: “joy” joined to either “he will add” or “God is gracious,” often felt as “joyful addition.”

Lettie flourished in the 19th and early 20th centuries across the English-speaking world, while Jo became stylish mid-century, making Lettie-Jo feel both vintage and newly fresh. Hyphenated double names are especially at home in the American South and in British naming traditions, and they’ve seen a quiet revival with the return of retro nicknames. Variants include Lettie Jo (unhyphenated), Letty-Jo, and Letty Jo; nicknames range from Lettie/Letty and Jo to the compact LJ.
