Biographical / Historical

Thomas Gregory Dabney was born on December 15, 1844, in Raymond, Mississippi (Hinds County). His parents, Augustine Lee and Elizabeth Osborne (Smith) Dabney, moved from Virginia to Mississippi in the 1830's, where Augustine L. Dabney was a lawyer in Raymond, the county seat. Thomas G. Dabney was the seventh of ten children. His brothers and sisters were Frederick Yeamans, Augustine Lee (who died in infancy), Ann Robinson, Elizabeth Osborne, Martha Camberlayne (who died during surgery of a tumor in the 1880's), Mary Smith, Marye, John Davis and Letitia Dabney.

Elizabeth (Lizzy) Dabney, Thomas’s sister, had a part in his early education; he then went to a boys’ school and then at age 13 Thomas and his brother Marye were sent to board at Oak Grove, the plantation home of John Curtis Williams, so they could attend school at Burleigh, the plantation home of their uncle, Colonel Thomas Smith Dabney.

In August 1858, Thomas had his first experience with engineering as a “stake marker” with his brother Fred, who was in charge of the preliminary railroad survey for the Gulf and Ship Island Railroad.

Thomas Gregory Dabney, at age 16, enlisted in Company A, 12th Mississippi Infantry, the :Raymond Fencibles,” in 1861. Wounded in 1862, Thomas recuperated at Manassas in Virginia, and by November 1862, he was a member of Company F, 1st Mississippi Light Artillery, and was considered an expert gunner. During the later years of the war Major Dabney fought in the Battle of Port Hudson and Ship Island and was a prisoner of war at Ship Island.

At the close of the war Major Dabney resumed his engineering work by becoming involved with the Louisiana levee systems, the Gulf and Ship Island Railroad, and the Vicksburg, Shreveport and Pacific Railroad, where he gained much experience. After the flood of 1884, when the entire Mississippi Delta was inundated, the Yazoo-Mississippi Delta Levee District was established. Thomas G. Dabney was chosen as Chief Engineer in April 1884, where he was to develop a levee system to protect the Delta from floods. From 1884 to 1920, Dabney remained the Chief Engineer where, with the expenditure of $15 million, he successfully achieved his goal of Delta flood protection. In June of 1920, he resigned his position because of age and physical means, but he was retained as consulting engineer until his death on March 5, 1929, at age 85. Throughout the country Dabney was consulted for his views, experience, and opinions relating to flood control; he was known as the “Dean of Levee Engineers.”

Thomas Gregory Dabney was married to Frances (Fanny/Fannie) Bowmar; they were the parents of seven children: Augustine Lee, Joseph Bowmar, Thomas G., Frederick Marye, James C., Elizabeth B., and Frances Mays Dabney. Joseph Hamilton Daviess Bowmar was father of Frances ("Fanny/Fannie") Bowmar, Dabney's wife. JHD's brother was Herman Bowmar Jr. (Bersailles,Kentucky), Herman Jr's son was Daniel Mayes Bowmar. Daniel Mayes Bowmar’s son was Aitcheson Alexander Bowmar (Editor, Woodford Sun newspaper, Versailles, Kentucky). AA Bowmar's daughter, Emily Bowmar, married H.F.van der Voort, Jr. of Dunkirk,New York. Their son, Thomas Lounsbury van der Voort married Elizabeth van der Voort

After Major Thomas Gregory Dabney’s death a monument was dedicated to his memory. The address on that occasion was delivered by Oscar Johnston on May 3, 1938, in Walls, Mississippi, at the foot of the Tennessee hills near Lakeview.
