Ordered to rest after her breakdown, Mary Anderson visited England. In 1890 she married Antonio Fernando de Navarro (1860–1932), an American sportsman and barrister of Basque extraction, who was a Papal Privy Chamberlain of the Sword and Cape. She became known as Mary Anderson de Navarro. They settled at Court Farm in the Cotswolds, Broadway, Worcestershire, where she cultivated an interest in music and became a noted hostess with a distinguished circle of musical, literary and ecclesiastical guests. She also gave birth to three children, one son who died at birth, another son, Alma Jose "Toty" Maria de Navarro (1896–1979) and a daughter, Mary Elena de Navarro, in her happy marriage.
