July 1421, Visconti was residing at the medieval Holy Trinity Minories (she may have been there as early as September 1411), which was similar to a nunnery but was also known as a place where women of high status and money would live together. It is believed that she lived in a townhouse built in 1352 by Elizabeth de Burgh, which had a reputation for housing women who were in tenuous political circumstances. Here, she lived a comfortable and well-kept life, but she was also engaged in business, being listed as an exporter of goods to Italy in 1423. Visconti's will bequeathed a portion of her unpaid dowry to various English nobles and other Italian immigrants, with the remainder (along with personal items) going to her steward, some ladies-in-waiting, her fool, and various religious institutions in Milan and England, including St. Mary Overy, Bourne Abbey in Lincolnshire (where Edmund was buried), and the Minoresses from Holy Trinity, but all of the recipients were equally unable to obtain the money from Milan. The bequests to religious recipients came with conditions to pray for herself and Edmund's souls. She died on 14 April 1424 and was buried in Austin Friars, London, which was a popular resting place for London's Italian immigrants. Her epitaph, written in Latin, focuses on her charm and beauty, her family and Milanese heritage, and does not mention her husband at all. It is preserved in a 16th-century document held in the British Museum, although the last part of it is untranslatable. Legacy As her dowry was never paid, the claims against it continued long after her death. Reprisals taken against Milanese merchants in London in 1464 to recover this sum were probably related to the dowry, and these grew to be so debilitating that the merchants were forced to stop trading with England in 1471, prompting Galeazzo Maria Sforza, the Duke of Milan, to ask his envoy in England to plead for relief. In 1486, a letter to the new Duke of Milan, Gian Galeazzo Sforza, demanded payment of the dowry. The Duke claimed to be unaware of such a debt at first, and three years later, ultimately declined the request as no documentation had been provided. Further reprisals took place in England in 1489, but the Duke was able to convince Henry to put a stop to them. However, Emperor FrederickIII issued separate letters of marque in
