Woodfin Hall Carmical was born on April 24, 1891, in Newnan, Georgia. The son of John Washington Carmical (1855-1919) and Martha Elizabeth Sewell Carmical (1858-1945), he was the third of seven children, which included: Frank Carmical (1898-1973), Grace Carmical (1896-1974), James Homer Carmical (1882-1967), Clyde Carmical (1885-1920), Bessie Carmical (1879-1949), and William Newton Carmical, Sr. (1893-1974). Hall Carmical attended the Fourth Congressional District A and M School, and graduated in 1914. While attending the Fourth District A and M, he played both football and baseball, and was a distinguished baseball player owing to the fact that he was ambidextrous and could pitch on successive days. In 1911, Hall Carmical's team was crowned Fourth District champions with Hall as pitcher. After Hall graduated, he remained at the Fourth District A and M School as an instructor in both the Departments of Mechanical Arts and Mechanical Drawing. Carmical remained in Carrollton as a teacher until at least 1920. While a teacher at the Fourth District A and M, Hall Carmical coached football and was a member of the Carrollton Baseball Club. Although Carmical taught at the Fourth District A and M School as late as 1920, he did leave Carroll County in 1917 to work with his brothers and to serve in the military. In "My Memory Book," he states "I knew I was going to 1st W. W. so I worked summer 1917 with Homer and Newt my bros. in SC." His brother, James Homer Carmical, in association with R. D. Cole and Co., ran a water tank erector company. During the summer of 1917 Carmical and his brother installed water tanks in Winnsboro, Orangeburg, and Columbia, South Carolina, all of which are pictured in Hall's "My Memory Book."

Carmical registered for the draft on June 5, 1917, and began serving on September 4, 1917. In September of 1917, Carmical was stationed at Camp Gordon, near Augusta, Georgia. Following Camp Gordon, Carmical was transferred to Camp Wheeler, near Macon, where he was assigned to the 118th Field Artillery Company, of the 31st "Dixie" Division. Towards the end of his service in the Army, Carmical was assigned to the 328th Fire Truck and Hose Company, which lead him to work in surrounding communities and even obtain special permission to enter the local towns for these duties. Carmical's service ended on April 28, 1919. After serving in the Army, Hall returned to Carroll County to teach, and in 1921, he traveled to many locations throughout the eastern United States, again working with his brothers' water tank erector company. The notable places that Carmical visited include Table Rock, Glassy Mountain, and Pickens, South Carolina; Devils Stool; Kings Mountain, North Carolina; Washington, D.C.; Baltimore, Maryland; New York City; Richmond and Petersburg, Virginia; Jacksonville, Florida; Montgomery, Alabama; Knoxville, Tennessee; and Louisville, Kentucky. Carmical also visited many Civil War sites in his travels.

Sometime between 1921 and 1925, Carmical returned to his home town of Newnan, Georgia, and is listed as a salesman in the Fourth District A and M alumni bulletin. Carmical would marry a Richburg, South Carolina, native, Pearle Mayben, sometime after 1927. He states in a hand written note in "My Vacation Book," "1926 or 7 I went on a picnic with my wife before we were married." The location he is referring to was Lake Lucile in Gaffney, South Carolina. According to his obituary, Carmical sold used car parts before he retired and was a member of the Coweta Lodge No. 60 of the Free and Acceptable Masons, and a member of the Atlanta based Yarab Temple of the Atlantic Order of the Nobles of the Mystic Shrine. Carmical also became an honorary member of the Branford Electric Railway Association (a non-profit and historical education institution which preserves trolley and railway cars), in 1962. Carmical's wife Pearle, who was a teacher, died on February 2, 1959, in Newnan. Hall died on November 20, 1981, and is buried with his wife at Oak Hill Cemetery, north of Newnan.
