Cleo

Derived from the Greek kleos, meaning glory or fame, most famously serving as the first half of Cleopatra. American parents adopted it as a freestanding name before the turn of the twentieth century, bypassing the four-syllable dynastic weight entirely. Early records show it serving boys and girls with equal informality before drifting permanently toward daughters.

Cleo sounds like a character who owns a cornet or drives a roadster with no roof. It carries the sharp, open-vowel snap of early modernist design. Living bearers cluster at the demographic extremes, skipping middle age almost entirely. It rarely requires a spelling correction, though people occasionally ask if there is a cat involved.
