Frances Ball was born on 9 January 1794 in Dublin, Ireland to John and Mable Clare Bennet Ball; the youngest of six children. Her father was a wealthy silk weaver. Catholicism was still suppressed in Ireland at this time, although her brother Nicholas later became one of the first Roman Catholic Irish judges. She was therefore sent to England at the age of nine to the Bar Convent in York, which was an IBVM school, although Mary Ward was not acknowledged as the foundress. This sisterhood, which had long existed in York, was originally established on the continent in the seventeenth century by Mary Ward to supply the means of a sound religious and secular education to young ladies. Henry James Coleridge describes her as "a bright, quiet, high-spirited girl, fond of fun, and with much depth of character." In these times students did not return home for Easter, Christmas or summer holidays. They stayed at the school, and lived like religious people, until they left school, usually in their late teens.
In 1807, her eldest sister, Cecilia was professed at the Ursuline convent in Cork. Frances travelled from Dublin to Cork for the ceremony, where she met Mary Aikenhead. Cecilia Ball took the name of Sister Francis Regis and was within a few years made Superior of the convent in Cork.[3] Upon the death of her father in 1808, Frances returned to Dublin.[1] Frances was expected to make an admirable wife for the son and heir of some rich Catholic Dublin merchant family.
In June 1814, under the direction of Dr. Daniel Murray, Archbishop of Dublin, Frances returned to York and entered the novitiate of the Institute of the Blessed Virgin Mary. There she received her religious training, and made her profession in September 1816, taking, in religion, the name of Mary Teresa.
