Joanna

Other forms of the name in English are Jan, Jane, Janet, Janice, Jean, and Jeanne.

In Greek this name became Ιωαννης Iōannēs, from which Iōanna was derived by giving it a feminine ending.

[1] Saint Joanna was culturally Hellenized, thus bearing the Grecian adaptation of a Jewish name, as was commonly done in her milieu.

[2] At the beginning of the Christian era, the names Iōanna and Iōannēs were already common in Judea.

[3] The name Joanna and its equivalents became popular for women "all at once" beginning in the 12th century in Navarre and the south of France.
