Allen Kendrick Albritton married on 9 August 1860 in Wilcox County Alabama to Penelope Ann Synthia Moore (28 Oct 1830–5 May 1879), the widow of Francis Marion Purifoy (4 Oct 1818–31 May 1858). Allen and his older brother, Matthew, enlisted in Company C, 44th Regiment Alabama Infantry on 31 March 1862 at Snow Hill, Alabama. Allen and Matthew became sick in the training camp and were sent home to Snow Hill on sick furlough in June, but both had returned to duty by June 30th. Allen’s officers reported him as present for duty between June 1862 and 17 February 1863, when he was sent to the Chimborazo Hospital in Richmond, Virginia, suffering from “Debility.” His brother, Matthew, was a patient at the same hospital, but rather than suffering from chronic diarrhea like Matthew, Allen had pneumonia. Medical officials transferred the Albritton brothers to the C.S.A. Hospital in Danville, Virginia on March 14th, and with both discharged and returned to duty on April 3rd.

On May 1st, Allen K. Albritton was wounded while on picket duty and sent back to the hospital on the 2nd. Medical officials issued him a wounded furlough on May 23rd, but his injury must have not proved serious, for he soon reported back to his unit and was present for duty from July 1863 through October 1864. Allen K. Albritton, along with his brothers John and Matthew, and their first cousin, William G. W. Albritton, were among the few men of Company C, 44th Alabama Regiment that Gen. Robert E. Lee surrendered at Appomattox Court House on 9 April 1865.

Like his brothers, Allen K. Albritton returned to farming at Snow Hill after the War (see statistics on his 1869–1870 farm given earlier). Sometime in the 1870s, Allen and Penelope moved with relatives to Texas, settling near Bazette, in Navarro County, with his brothers and sister by the latter 1870s. On 5 May 1879, while at the residence of Mr. Jennings, lightning struck and killed Penelope. Allen K. Albritton married on 8 January 1880 in Navarro County Texas to Sarah A. Dayton (8 July 1849–20 July 1883), and in mid-1880, they lived on Allen’s Navarro County farm with his three sons from his first marriage. Three months after Sarah’s death, on 21 October 1883, Allen married for the third time to Mary Ellen Watt (28 May 1848–31 Aug 1923), daughter of James Richard Watt and Eliza Sarah Moore, both natives of England who had immigrated to Canada by the time of Mary’s birth. Mary married to a Mr. Wright in Canada and had a daughter, Etaglinza Ann Wright [Ettia, Nettie] (12 Nov 1871–18 Mar 1946), before divorcing. The extended Watt family emigrated from Canada sometime after 1871 and settled near Bazette, in Navarro County Texas, by 1876, when Mary’s mother died. On 2 February 1888, Nettie Wright married William Dow Sessions (9 Dec 1859–26 Mar 1916), with the ceremony conducted by her step-uncle, George W. Albritton. Nettie and Sessions presumably divorced, and she remarried on 25 October 1892, she remarried to Martial Leonidas Purifoy (2 July 1854–17 June 1918), the son of Allen K. Albritton’s first wife, Penelope (so Nettie married her step-brother).

Allen and Mary had two sons of their own, Allen and William Albritton, and they farmed in Navarro County until his death.
