History & Origin

Lethia is an extended form of Letha, and its origin is genuinely double-edged. It may echo the Greek Lethe, the mythic river of forgetfulness, or it may soften Alethea, 'truth.' Early-nineteen-hundreds American families used it without settling the question.

It was always rare, given to only a couple dozen girls a year around 1917 and thinning long after. A girl named Lethia then would be past a hundred today, of a great-grandmother generation.

Did you know? Lethia's roots split two ways in Greek, toward Lethe, the river of forgetfulness, or Alethea, its near-opposite meaning 'truth.'
