From “Virginia and Virginians, 1606-1888,” published by H.H. Hardesty, we find this entry for Thomas Buchanan, who resided at Logan Court House, West Virginia:

Was born in Tazewell county, Va., Nov. 26, 1821; his wife, nee Mary Ellis, in Logan county, W.Va., Oct. 12, 1817; they were joined in wedlock in her native county, July 27, 1843. The only child of this marriage is Floyd Buchanan, who was born in Logan county, W.Va., Feb. 24, 1849; he was married in this county June 10, 1869, to Eliza Ann Williams, who was born in Raleigh county, W.Va., June 9, 1852. The children of this union are: Charles B., born Aug. 22, 1870; Thomas, born March 28, 1873; Mary, born May 19, 1876, died Jan. 6, 1888; John, born Feb. 8, 1879, died Dec. 24, 1887; James, born Jan. 10, 1882; George, born Jan. 20, 1885, died Dec. 23, 1887; Lillie May, born Feb. 27, 1889. The Buchanan family is one of the oldest and most highly honored in Logan county. During the late war the subject of this sketch enlisted in the 4th W.Va. V.C.; served through the war as second lieutenant, and was honorably discharged in 1865, at Wheeling. As a private citizen he has filled many offices of trust. He was appointed assessor by State Auditor, held the office two years; was then elected recorder of Logan county, and held this office two years; was next elected clerk of the court, which office he also held during two years, and was at the same time clerk of board of supervisors. He was postmaster for six years, and has at one time held seven offices of importance. No man in the county stands higher, or is more beloved by his acquaintances. He owns extensive coal and timber lands in Logan county, where he now resides at his beautiful home on Guyandotte River, near Logan Court House; this town is his post office.
