Lucia Visconti was born in 1372 in Milan, the daughter of Bernabò Visconte, Lord of Milan. Members of the Visconti household were the rulers of Milan from 1277 to 1447. Her father was murdered in 1385. In the midst of a turbulent period in Milanese history, a contract was drawn up in May 1406 for her to marry Edmund Holland, Earl of Kent. A substantial dowry payable over a number of years was welcomed by the impoverished household of the young man.
The marriage took place at the church of St Mary Overy in Southwark on 24 January 1407 and was attended by Henry IV. In September 1408, four months after Lucia had received her letters of denisation, Edmund was killed in Brittany. Lucia remained in England for the rest of her life. In 1411 she gained papal permission to reside within a nunnery of her choice. She took up residence in the precinct of the London Minoresses (hence the word Minories) in Aldgate, a common place of retreat for noble widows. She died in April 1424 and was buried in the church of the Austin Friars.
