John Martin Hamley,[Democratic Party (United States)|] Sr., served from 1912 to 1924 as a Democrat in the Louisiana House of Representatives from East Carroll Parish in far northeastern Louisiana. Hamley was born in Lake Providence, the first son of Edward J. Hamley, a native of St. Louis, Missouri. The Hamleys moved to East Carroll Parish in 1878. Edward Hamley was mayor of Lake Providence for twelve years. John Hamley's mother, Annie Malam Hamley, was born in Bavaria; in the 1860s, her family migrated to the United States. John and Edward Hamley were partners in the real estate business. Hamley's younger brothers were Edward D. Hamley, William Hugh Hamley, and Joseph Celestin Hamley. After his three terms in the state House of Representatives, Hamley served from 1924 to 1931 as the House clerk, a position chosen by the members. In 1933, he was elected East Carroll Parish tax assessor. He was also a member of the Louisiana Flood Control Committee, a group interested in the prevention of a future Great Mississippi Flood of 1927. In 1914, Hamley married Katie Ransdell, the daughter of Judge Francis Xavier Ransdell of the Louisiana 6th Judicial District Court and his wife, the former Katie Blackburn Davis. Katie, or "Kate", was a paternal niece of U.S. Senator Joseph E. Ransdell, also of Lake Providence. The Hamley children attended the St. Patrick's Catholic Churchparochial school in Lake Providence; the daughters thereafter attended Maryville University, then Maryville College in St. Louis. There were eight Hamley children: Edward Ransdell Hamley, Mary Hamley Marron, Katherine Hamley Bernacchi John Martin Hamley, Jr., Stuart Douglas Hamley, Madeline Hamley Howington, Elizabeth Hamley Lewis, Hamley was a brother-in-law of Judge Frank Voelker, Sr., who in 1937 succeeded Francis Ransdell on the Louisiana 6th Judicial District Court, of which the long-term district attorney was Jefferson B. Snyder. Voelker was married to the former Isabel Ransdell, a sister of Katie Ransdell. Hamley died in Vicksburg, Mississippi. The Hamleys are interred at Lake Providence Cemetery. There is confusion about his middle name "Martian", which appears on his tombstone. A cenotaph dedicated to the youngest of the Hamley sons is posted as John Martin Hamley, Jr., who died at the age of twenty-three while serving as an ensign in the United States Navy during World War II. Hamley, Jr., is buried at the Honolulu National Cemetery. The Louisiana House membership listing spells Hamley's middle name as "Martin."
