The name Susannah has its origins in the Hebrew language, derived from the biblical name Shoshannah, which means "lily" or "rose." This name can be traced back to ancient times, around the 6th century BC, and was popularized through its use in the Old Testament's Book of Daniel.

In the apocryphal Book of Susanna, part of the Greek Septuagint, the name is borne by the virtuous wife of a wealthy Jew living in Babylon. Her story of resisting the advances of lecherous elders and being vindicated was widely known in early Christianity, contributing to the name's enduring appeal.

One of the earliest recorded examples of the name Susannah is found in the Bible's Book of Luke, where a woman named Susannah is mentioned among those who provided for Jesus and his disciples out of their resources. This biblical reference further solidified the name's association with piety and devotion.

Throughout history, several notable individuals have borne the name Susannah.
