Saint Emerentiana (†304) was a Roman martyr, foster-sister of St. Agnes who lived around the start of the 4th century. St. Agnes was a rich Roman heiress who was martyred after refusing her engagement due to her Christian religion. A few days after Agnes' death, Emerentiana, who was a catechumen still learning about Christianity before being officially baptized, went to the tomb to pray and was suddenly attacked by the pagans and stoned to death by the crowd. Her tomb is in the church of Sant'Agnese fuori le mura in Rome and her feast day is January 23. She is known to assist in stomach problems.
