From Wiki:
Minnehaha is a fictional
Native American woman documented in
Henry Wadsworth Longfellow's 1855 epic poem
The Song of Hiawatha. She is the lover of the titular protagonist
Hiawatha. The name is often incorrectly said to mean "laughing water", though in reality it translates to "waterfall" or "rapid water" in
Dakota.[SUP]
[1][/SUP] She is the subject of the poem, and later song, cantata, and painting,
The Death of Minnehaha.
