Daniel Harnbright Mabry (Russell, Patrick, Joel, Ephraim, Hinchia, Francis) was born on 8 April 1840 in Benton (now Calhoun) County, Alabama, the fifth of six children born to Russell A. Mabry and his first wife, Ann Champion. It is likely that Daniel's mother, Ann, died at the time of the birth of Daniel's younger sister, Nancy Ann Mabry, about 1843 or shortly thereafter. Daniel was only six years old when his father moved to Hunt County, Texas and married his second wife, Mary Atterberry and only twelve years old when his step mother died giving birth to his half brother, Albert Pinkney Mabry in December 1852. A short time later his father married Mary Atterberry's sister, Sarah Atterberry.

When the Civil War began it seemed like every young male in the south either volunteered or was drafted into the Confederate Army. Russell Mabry had five sons old enough to fight and all five of them served as Confederate soldiers. What may be even more unusual is that all five of them survived the War and returned home when it was over. The only member of the family who did survive the War was Russell Mabry, who died sometime in 1865 while on a trip to Arkansas to take supplies to his five soldiers sons.

Daniel H. Mabry enlisted on 20 Aug 1861 at Waxahachie, Texas in a local cavalry company, know as the Ellis County Blues under Col. William H. Parsons. This unit was later became Company H. of the 12th Texas Cavalry, C. S. A. His name is shown on a muster roll of Parson's Regiment of Texas Mounted Volunteers at Camp Hebert near Hempstead, Arkansas on 28 October 1861.

Daniel Harnbright Mabry was first married on 18 August 1867 to Mary Elizabeth McKey by whom he had two children. After her death, which probably occurred in 1871 or early 1872, he married a second time in Cleburne, Texas on 19 September 1872 to Rachel Belle Murdock, daughter of John M. Murdock and Nancy R. Goodnight. Daniel and Rachel had ten children. Daniel Mabry died on 30 September 1898 and his widow, Rachel, died 17 February 1929 in Mineral Wells, Texas. They are buried in Block A, Lot 28 of the Elmwood Cemetery in Bowie, Texas.
