Mary Scott, 3rd Countess of Buccleuch and Countess of Tarras (31 August 1647 – 11 March 1661) was a young Scottish peer, the daughter of Francis Scott, 2nd Earl of Buccleuch.
 Mary succeeded to her father's titles aged 4, when he died in 1651.
 She immediately became one of the most desirable matches of the kingdom.
 On 9 February 1659, she married Walter Scott of Highchester (herself only 11 years old at the time and her husband, 14), who was created Earl of Tarras a year later.
 Her mother arranged the marriage without proclamation, with a warrant from the presbytery of Kirkcaldy.
 It created a lot of noise at the time and the court ruled that Mary should be separated from her husband until she was 12 years of age.
 During their separation they continued a very affectionate correspondence.
 However, she fell ill and died two years after their reunion, aged 13 in 1661 and her titles passed to her sister, Anne.

The Jude–Crutcher House (also known as the George Jude House and the David and Lucy Crutcher House) is a historic plantation house in Huntsville, Alabama.
 The house was built circa 1812 on land deeded that year to Samuel Echols.
 Echols sold 54 acres and the house to George Jude, Sr., in 1817.
 Jude died two years later, leaving the land to his son, George Jr.
 The younger Jude eventually acquired 800 acres (325 ha) and owned 31 slaves.
 Upon his death in 1873, the land stayed in the family until 1883.
 In 1906 David Crutcher, who had been born a slave on an adjacent plantation in 1851, purchased the house and 154 acres (62 ha) along with two other African-American men.
 The Crutchers operated a successful farm on their portion of the land, which was an extension farm for Alabama A&M University until the 1940s.
 Only 7% of African-American farmers in Madison County in 1910 owned their own farms.
 David died in 1924, and his wife, Lucy, died in 1943, although the house and land is still in the family.
Turner Ashby, Jr. (October 23, 1828 – June 6, 1862) was a Confederate cavalry commander in the American Civil War.
 He had achieved prominence as Thomas J. "Stonewall" Jackson's cavalry commander, with the rank of colonel, in the Shenandoah Valley before he was killed in the Battle of Good's Farm.
 Although he is sometimes referred to as a general and his name often appears in lists of Confederate generals, his appointment as brigadier general was never confirmed by the Confederate Senate.
 He died two weeks after his appointment and the Confederate Senate did not act to confirm the appointment during that time.
