Isabella Dinsmore Greenway (née Selmes; born March 22, 1886 – December 18, 1953) was an American politician who was the first congresswoman in Arizona history, and as the founder of the Arizona Inn of Tucson. During her life she was also noted as a one-time owner and operator of Los Angeles-based Gilpin Airlines, a speaker at the 1932 Democratic National Convention, and a bridesmaid at the wedding of Eleanor and Franklin D. Roosevelt. Early life Isabella Dinsmore Selmes was born the daughter of Tilden Russell Selmes (1835–1895) and Martha "Patty" Macomb Flandrau (1861–1923). Isabella was born at the historic Dinsmore Farm in Boone County, Kentucky which was owned by her mother's maternal great aunt Julia Stockton Dinsmore (1833–1926). Tilden Selmes was general counsel for the Northern Pacific Railroad. Patty Flandrau was the daughter of Minnesota judge and politician Charles Eugene Flandrau (1828–1903) and his first wife Isabella Ramsay Dinsmore (1830–1867). The Selmes family owned a ranch in the Dakota Territory that was close to Theodore Roosevelt's ranch and they developed a close friendship with each other. After the untimely death of her father in 1895, Isabella and her mother lived with various members of her mother's family in Kentucky, Minnesota, and New York. Isabella attended Miss Chapin's School in New York City, where she met and became lifelong friends with Roosevelt's niece, Eleanor. First and second marriages In 1905, Isabella was one of Eleanor's bridesmaids when Eleanor Roosevelt married Franklin Delano Roosevelt. Shortly thereafter, while the Roosevelts were on their honeymoon, Isabella married Robert Munro-Ferguson (1867–1922), the younger brother of Ronald Munro-Furguson (1860–1934). Robert was a family friend of the Roosevelts, as well as one of Theodore Roosevelt's Rough Riders. Robert and Isabella became the godparents of Franklin and Eleanor's only daughter, Anna Eleanor Roosevelt. Three years into the marriage, Robert contracted tuberculosis and in 1910 the couple moved to the dry climate of New Mexico, hoping his health would improve. There Isabella nursed her husband and educated their two children; Robert, Jr. (1908) and Martha (1906). During this period, Isabella and Eleanor established a close correspondence that continued for the rest of their lives. After Robert's death in 1922, Isabella married a close friend, Gen. John Campbell Greenway (1872–1926), another of Roosevelt's Rough Riders, whom she had met in 1911. John moved the family to a ranch in Arizona near Bisbee where he was manager of the Calumet and
