[5] Angelina was married at age 15 to Giovanni da Terni, the Count of Civitella del Tronto, in the Abruzzo region, within the Kingdom of Naples, but he died only two years later, leaving her a childless widow.

She was clothed as a Franciscan tertiary and, with several companions, began an apostolic mission around the countryside of the kingdom, preaching the values of repentance and virginity, as well as service to those in need.

Angelina defended herself before Ladislas, the King of Naples, who dismissed the charges, but expelled her and her companions from the kingdom, in order to avoid further complaints.

[4] Angelina then went to Assisi, where she stopped to rest and to pray at the Basilica of Santa Maria degli Angeli, the cradle of the Franciscan Order.

Known as the "Monastery of the Countesses"—due to the social standing of most of its members, he had established it out of his vision of having these noble women of the city serve as an evangelizing force in their society.

Angelina had to submit and, in a public ceremony held in the friars' church in Foligno on 5 November 1430, vowed obedience to the local minister provincial.

To avoid the potential for future repetition of this conflict, the congregation put itsel under the obedience of their local bishops, with their spiritual direction to come from the friars of the Third Order Regular of St. Francis of Penance.

In 1428, they had been put briefly by Pope Martin V under the jurisdiction of the Friars Minor, with a specific mandate for the education and instruction of young girls.

Even so, their work was fairly apostolic until they were required to become an enclosed religious order in 1617, having taken solemn vows with a strict separation from the affairs of the external world, limited to the education of girls within the cloister.
