Margaret Deane Smith Ross was born August 24, 1922 in Central Arkansas.  She attended both what is now Arkansas Tech University and the University of Arkansas. A journalism major at the latter, she left the university before graduating to marry Captain Edwin L. Ross in September 1942; he was killed in combat in Normandy on July 4, 1944.

Following the death of her husband, she lived in Little Rock and worked as a freelance writer for the Arkansas Democrat. In 1953 she became an associate editor of the Arkansas Historical Quarterly, a position she retained until 1993. She was a charter member of the Pulaski County Historical Society, and from 1953 to 1957 served as its journal’s first editor. From 1954 to 1957 she was a research assistant at Arkansas History Commission.

In 1957 she became the Arkansas Gazette historian and curator of the J.N. Heiskell Collection of Arkansiana; she remained with the Gazette for twenty-seven years. From 1958 to 1968 she wrote a historical column for the Gazette, the “Chronicles of Arkansas.” She was a charter member of the Arkansas Genealogical Society, founded by Walter Lemke in 1962. In 1968 she became a member of the Arkansas Historical Association’s board of directors, a position she occupied until 1980. In 1969 she published a book, Arkansas Gazette: The Early Years, 1819-1866: A History; it received the Award of Merit from the American Association for State and Local History. From 1979 to 1984 she wrote “Grass Roots,” a genealogical column for the Gazette. Also in 1979 she became the first fellow of the Arkansas Museum of Science and History. In April 2000 she received a lifetime achievement award from the Arkansas Historical Association.

As a historian for the Gazette, she became the de facto historian for the State of Arkansas.  Her knowledge of Arkansas history was unsurpassed during her lifetime.  She also served as an unofficial teacher to generations who were interested in learning more about the history of their state, and how to do that research.

She died in Little Rock in December 2002.
