Genevieve Brady, Duchess of the Holy Roman Church (later Macaulay, née Garvan; April 11, 1880 – November 24, 1938) was an American philanthropist and patron of Catholic charities.

[5] During World War I she purchased the Old Colony Club in New York City and lent it to the United States government as a mobilization center for nurses training for service in Europe.

After the war she was decorated by the French government for her financial aid to refugees and was awarded the Order of the Crown by Albert I of Belgium.

[5][6] In the 1920s, Garvan and her husband spent winters at the palace Casa del Sole in Rome to work within Vatican affairs.

Under First Lady Eleanor Roosevelt she served as vice chair of the National Women's Committee on Welfare and Relief Mobilization.

They entertained and hosted various high-ranking Catholic officials, including Francis Spellman and the future Pope Pius XII.

[13] In 1937, she gifted the estate, including 250 acres of land and an 87-room mansion, to the New York Province of the Society of Jesus,[2] which used it as a seminary before converting it into the St. Ignatius Jesuit Retreat House in 1963.
