Schumm first married – on July 29, 1931, in Los Angeles – Agnes Mellen Kent (1888–1975), who from a previous marriage, had two daughters – (i) Jessie Marcellina (Elizabeth) Olivieri (1918–1947) and (ii) Josephine Tarquini (1910–2010), that latter having been adopted after being rescued from the 1915 earthquake in central Italy. Agnes Kent was the daughter of New York architect William Winthrop Kent (1860–1955) – who, as architect, was affiliated at various times with (i) Harvey L. Page, (ii) his brother, Edward Austin Kent (who perished on the Titanic), (iii) Heins &amp; LaFarge, and (iv) Jardine, Kent &amp; Jardine. He was one of the architects of the original plan for Cathedral of St. John the Divine, including the Romanesque Revival apse. Agnes was also the granddaughter of Henry Mellen Kent (1823–1894), one of the founders of the Flint &amp; Kent department store in Buffalo. Hans and Agnes divorced. Agnes had been previously married to Umberto Olivieri (1884–1973), a banker for 14 years at Bank of America in San Francisco, a lawyer in Rome, and a language professor for 30 years at Santa Clara University, who, in 1958, at the age of 74 — after returning to Italy and joining the Order of Saint Benedict at the Subiaco Monastery in Rome — became ordained as a Roman Catholic Priest by the Bishop of Tivoli at Subiaco. Hans Schumm was Agnes' second of three husbands.
