Historical Note

John William Mackay was born in Dublin, Ireland in 1831 to a working-class family. They immigrated to the United States when Mackay was nine years old, settling in New York City. In 1851, Mackay sailed to California in the search of gold. In 1859, that search took him to Virginia City, Nevada, where he became known as one of the Bonanza Kings, a group of four men who struck one of the largest silver lodes ever found.

In 1866, Mackay married Marie Louise Bryant Hungerford. They had two children: John William, Jr. (1870), and Clarence Hungerford (1874-1948). Although the family's fortune was made in Nevada, the family spent nearly all their time in San Francisco and New York.

As successful as his father, Clarence Hungerford Mackay made his fortune as the chairman of the board of the Postal Telegraph and Cable Corporation and president of the Mackay Radio and Telegraph Company. He married Katherine Duer (1878–1930) in New York on May 17, 1898. They had three children: Katherine (1900-1971), Ellin (1903-1988), and John William III (1907-1988). Katherine and Clarence divorced in 1910. Katherine Duer remarried in Paris, changing her name to Blake, but was divorced in 1914.

Katherine and Clarence's children grew up in New York and attended school there. Katherine married Kenneth O'Brien (1895-1954) in 1922, though their marriage ended in divorce. In 1938, she married Robert Ziemer Hawkins (1903-1979). Ellin, an accomplished author, married composer Irving Berlin (1888-1989) in 1926. Son John married Josephine Gwendolyn Rose (1908-2004) in 1929.
