Susannah (שׁוֹשַׁנָּה) comes from the Hebrew shoshannah, meaning "lily." In the Old Testament Apocrypha, Susanna is the heroine wrongly accused by two elders and vindicated by the young Daniel.
Susannah peaked at #225 in the U.S. in 1985. Stephen Foster's 1848 song "Oh! Susanna" made the name an American standard.
Susannah reduces to four — the number of biblical vindication.
