William Starr Miller II (October 26, 1856 - September 14, 1935) was a prominent New York industrialist and real estate operator.
Born in New York City, William Starr Miller II was a son of George Norton Miller I (1805-1891) and Sarah Caroline Tucker Chase (Chace) (1832-1872). It appears that William II was named in honor of his father's brother of the same name, William S. Miller (William Starr Miller I) (1793-1854). William I died about two years before William II was born.
William II's parents George and Sarah were married on October 9, 1855 in Boston, Massachusetts. William Starr Miller II attended Harvard University from 1874–1878, graduating with an A.B. degree in 1878. He then attended Columbia Law School, where he graduated in 1880 with an LL.B. degree. He was admitted to the New York City Bar Association the same year. William II's original business address was 39 Fifth Avenue, Manhattan, New York.
William II married Edith Caroline Warren (April 15, 1866 - May 17, 1944) on April 28, 1886. She was a daughter of George Henry Warren (November 8, 1823 - April 8, 1892) and Mary Caroline Phoenix (February 27, 1832 - January 18, 1901). George H. Warren was one of the founders of the New York Metropolitan Opera. Edith Warren's brother was the architect Whitney Warren, a partner in Warren and Wetmore.
William Starr Miller II had one daughter, the writer Edith Starr Miller (Lady Queenborough) (1887-1933), who was the co-author (with Paquita de Shishmareff) (1882-1970) of Occult Theocrasy (2 vols.) (Chatou, France: British American Press, 1931), a famous conspiracy classic dealing with the Order of the Illuminati (founded in Bavaria, Germany on May 1, 1776 by Adam Weishaupt) and other secret societies.
The Millers commissioned Whitney Warren to design them a French Norman-style "cottage" in Newport, Rhode Island named High Tide, with interiors by noted designer Ogden Codman. They turned to architects Carrère and Hastings, however, for their New York City residence at 1048 Fifth Avenue, in Manhattan. This house became the Neue Galerie in 2001.
