Mary Ramsey Wood aka Mary Ramsey Lemons Wood (May 20, 1787/circa 1810 (disputed) – January 1, 1908) was an American pioneer known as the "Mother Queen of Oregon".
 She was reported to be the oldest living person in the United States when she died, supposedly at the age of 120.
 It is said she traveled to the Oregon Territory across the Oregon Trail at the age of 66.
 There is evidence this age claim was inaccurate or exaggerated, however, and she may have been between 96 and 98 when she died.
Garrard Sliger "Buster" Ramsey (March 16, 1920 – September 16, 2007) was an American football player who starred at William and Mary and was the first head coach of the American Football League's Buffalo Bills in 1960.
 Prior to coaching the Bills, and after a stint in the United States Navy during World War II, Ramsey played for the Chicago Cardinals of the National Football League (NFL) from 1946 to 1951 and a member of the 1947 NFL Champions.
 In 1951, Ramsey became a player-coach for the Cardinals before becoming the defensive coach for the Detroit Lions in 1952.
 During his tenure with the Lions, Ramsey is credited with devising the 4-3 defense, a staple of modern football, and being the first coach to blitz linebackers, a package he called Red Dog.
 The Lions won three World Championships in the 1950s with Ramsey running the defense.
 He developed Lions greats such as Yale Lary, Jack Christiansen, Jim David, and many others.
 In 1960, he was lured to the new AFL as coach of the Buffalo Bills.
 Though fired by Bills' owner Ralph C. Wilson Jr. after the 1961 AFL season, Ramsey is credited for laying the foundation of one of the best defensive teams in the history of the AFL.
 He also had a brother, Knox Ramsey, who also starred for the College of William and Mary, the Chicago Cardinals, and the Washington Redskins.
 Ramsey was elected into the Virginia Sports Hall of Fame in 1974, and the College Football Hall of Fame in 1978.
John & Mary is a United States-based folk rock duo featuring John Lombardo and Mary Ramsey both members or former members of alternative rock band 10,000 Maniacs.
Extended Versions is a live album by 10,000 Maniacs released in 2009 as a part of the Extended Versions collection of discounted albums.
 The album was recorded during the band's 2006 tour with Oskar Saville as lead vocalist.
 By the time of the album's release, Saville had been replaced as lead vocalist by the former member Mary Ramsey who is pictured on the cover and listed as a member of the band.
Victory Gardens (1991) is the debut album from John & Mary, recorded in 1990 just six months after the two met in December 1989 and immediately following their signing with Rykodisc.
 John Lombardo, former member of 10,000 Maniacs and responsible for much of their early music, brought elements of the early Maniacs sound with him.
 Combined with the classically trained Mary Ramsey's blend of folk and classical influences, the album is considered by some to be heir to the 10,000 Maniacs album "The Wishing Chair" (1985), critically acclaimed for linking traditional influences with the contemporary new-wave sound.
Our Time in Eden is the fifth studio album by American alternative rock band 10,000 Maniacs.
 It was released in 1992 on Elektra Records.
 The release is 10,000 Maniacs' last studio album with the original lead singer, Natalie Merchant.
 The album included her future replacement Mary Ramsey on violin and viola on such tracks as "Stockton Gala Days" and "How You've Grown".
 Singles released from the album were "These Are Days", "Candy Everybody Wants" and "Few and Far Between".
 The brass and woodwind section is covered by the J.B.'s, or James Brown's band.
Love Among the Ruins (1997) was the first album released by 10,000 Maniacs with their new lead singer, Mary Ramsey, after Natalie Merchant left in 1993.
 The two singles from the album, "More Than This" and "Rainy Day", were not originally intended to be included on the album at all.
 John Lombardo had just written "Rainy Day", which was deemed more radio friendly than the other songs, and the record company insisted that the band record a cover song for inclusion.
 The band chose to credit the songs as group collaborations so that all members would receive equal royalties.
 Ramsey and Lombardo shared the lyric writing.
 Ramsey wrote the music to "All That Never Happens".
 Lombardo wrote "Rainy Day", "Even with My Eyes Closed", "Big Star", "Shining Light" and "Across the Fields".
 Lombardo shared a writing credit with Jerry Augustyniak on "Girl on a Train".
 Rob Buck wrote "Love Among the Ruins", and Dennis Drew wrote "A Room For Everything".
 A live version was also included on their 2016 album "Playing Favorites".
