Virgin Eustochium of Bethlehem (Orthodox veneration unconfirmed)

Eustochium, secular name Julia, was the daughter of Senator Toxotius and Venerable Paula of Rome. Following her mother's example, she became the first known Roman noblewoman to vow perpetual virginity. She studied under Blessed Jerome of Stridon in Rome, and in 385 followed him together with her mother to Bethlehem, where she mastered Hebrew and Greek; several of Jerome's biblical commentaries were dedicated to her. After her mother's death in 404, she headed the convent her mother had founded in Bethlehem, and cared for refugees after the sack of Rome in 410. She died in 418 or 419.

IMPORTANT CAVEAT: a targeted check of azbyka.ru, drevo-info.ru, and pravenc.ru found NO individual feast day for Eustochium in the Orthodox calendar. Azbyka.ru has no dedicated hagiography page. Drevo-info.ru gives September 28 with reference to the "Italo-Western tradition." The Russian Wikipedia infobox scopes the feast day explicitly to the Catholic tradition. Thus Eustochium is a genuine historical ascetic, but no reliable evidence of independent veneration in the Orthodox Church was found; this entry should be handled with caution.
