Banker and prominent social figure in New York and Newport Society. Morris was born on June 4, 1882 in Newport, Rhode Island. He was the son of Francis Morris (1845–1883) and Harriet Hall (née Bedlow) Morris (1849–1923). After his father's death, his mother married John Rex Guelph-Norman (1861–1932), who claimed to be the son of King Edward VII and rightful heir to the throne, in 1898. They divorced after she discovered he had a wife in India. His paternal grandparents were Lewis Gouverneur Morris, for whom he was named, and Emily (née Lorillard) Morris (1839–1850). His maternal grandparents were Henry Bedlow (1821–1914) and Josephine Maria (née de Wolf Homer) Bedlow (1831–1896). He was first cousin of Emily Lorillard Morris (b. 1873), who married Rolaz Horace Gallatin (d. 1948), a cousin of Albert Eugene Gallatin and nephew of Commodore Elbridge Thomas Gerry, in April 1896. Morris graduated from Harvard University in 1906. He was a former member of the New York Stock Exchange. In 1915, Morris organized Morris & Pope, an investment firm. In the spring of 1917, the firm failed which left Morris heavily in debt. He was imprisoned in Westchester County, from June 18, 1921 until October 5, 1921, as a debtor. He was eventually discharged as an honest insolvent debtor. New York directory listings indicate that, after his failure in 1917, Morris did not re-entered the business world. Morris served as a trustee of the Museum of the City of New York. In 1908, he married Alletta Nathalie Lorillard Bailey (1883–1935), an amateur architectural historian and photographer. She was the daughter of James Muhlenberg Bailey (1839–1897) and Alletta Remsen (née Lynch) Bailey (1870–1930), and a granddaughter of Nathaniel Platt Bailey. She was also a descendant of Robert Livingston, first Lord of Livingston Manor, Robert R. Livingston of Clermont. They were actually distant cousins, both being great-grandchildren of Jacob Lorillard, the son of Pierre Abraham Lorillard, founder of the Lorillard Tobacco Company. In 1946, Morris married Anita Rhinelander (née Stewart) Braganza (1886–1977) in New York City. Morris died at the age of 85, on August 14, 1967 at his home in Newport, Rhode Island.
