Popularity: The name Lean ranked 3628th in popularity for females of all ages in a sample of the 1990 US Census.

Narrative: This could be a compound of Lee and Ann, or a variation of Lianne. If the latter, it could be a short form of Julianne, or could be derived (rather distantly) from the French name Eliane.
