A historian has identified the great-grandmother of Jesus.
According to Florentine medieval manuscripts analyzed by a historian, the great-grandmother of Jesus was a woman named St. Ismeria.
St. Ismeria likely served as a role model for older women during the 14th and 15th centuries.
The legend of St. Ismeria sheds light on both the Biblical Virgin Mary's family and also on religious and cultural values of 14th-century Florence.
Lawless studied the St. Ismeria story, which she said has been "ignored by scholars," in two manuscripts: the 14th century "MS Panciatichiano 40" of Florence's National Central Library and the 15th century "MS 1052" of the Riccardiana Library, also in Florence.
"According to the legend, Ismeria is the daughter of Nabon of the people of Judea, and of the tribe of King David," wrote Lawless.
She married "Santo Liseo," who is described as "a patriarch of the people of God." The legend continues that the couple had a daughter named Anne who married Joachim. After 12 years, Liseo died. Relatives then left Ismeria penniless.
