Margaretha

Margaretha is a Dutch, Swedish, and German form of Margaret, ultimately derived from the ancient Greek margaritēs, meaning pearl, which itself was borrowed from an Old Persian or Sanskrit source. The name spread widely across medieval Europe through the cult of Saint Margaret of Antioch, a popular martyr venerated for her legendary courage. Notable bearers include Margaretha Geertruida Zelle, better known by her stage name Mata Hari, the Dutch exotic dancer and wartime spy. Related forms include Margareta, Marguerite, Margherita, and Gretchen.
