Problem: John McAllister Schofield was born September 29, 1831, in Gerry, Chautauqua County, New York, son of Rev. James Schofield (1801-1888) and his first wife, the former Caroline (McAllister) Schofield (1810-1857). His father, a Baptist minister in Sinclairville became a domestic missionary and moved his family (which then included six children and would include 10 who survived infancy) to Bristol, Illinois. When John was 12, they finally settled in Freeport, Illinois, where Rev. Schofield became the town's first Baptist minister in 1845, and where he would ultimately be buried in 1888. As a young man John Schofield was educated in the public schools, helped his family farm and build their home, and then surveyed land in northern Wisconsin before spending a year teaching school in Oneco, Illinois not far from Freeport.

John Schofield married Harriet Whitehorn Bartlett, daughter of W.F.C. Bartlett (Chairman of West Point's Department of Philosophy) and they would have two daughters and four sons. Two sons, John (1858-1868) and Henry (1862-1863), died before reaching adulthood. William Bartlett Schofield, 1860-1906) survived to and began a U.S. Army career, rising to Major, as did Richmond McAlister Schofield (1867-1941). After Harriet died in 1888, she was buried with her father and son John in the United States Military Academy Post cemetery. At age 60, in Keokuk, Iowa in June 1891, Schofield remarried, to 27 year old Georgia Wells Kilbourne, with whom he had a daughter, Georgiana.  Georgia Wells Kilbourne was a native of Keokuk, Iowa. She was the daughter of George Kilbourne, and was named Georgia for her father. She attended school in New York, and afterwards studied abroad. General Schofield and Kilbourne were married in 1891. Her mother, Mrs. Kilbourne, and her younger sister, Miss Emma Kilbourne, spent a part of the year at her Washington home. Emma Kilbourne had a literary predilection, devoting much of her time to reading and study.  During his military career, perhaps because of his reformer image, Schofield would be dogged by accusations of favoritism toward family members. His brother George Wheeler Schofield (1833-1882) would also become a brevet Brigadier General of U.S. Volunteers during the American Civil War, originally volunteering with the 1st Missouri Volunteer Infantry in November 1861 and promoted to Captain in the 1st Missouri Light Artillery after the Siege of Vicksburg, and rising to command the 2nd Regiment Missouri Volunteer Light artillery and ultimately being commissioned as a Major in the Regular Army after the Civil War and serving in the 10th Cavalry and later the 6th Cavalry on the Western Frontier, and for whom the .45 caliber Smith and Wesson Schofield revolver was named. Another brother Charles Brewster Schofield (1849-1901) would graduate from West Point in 1870. C.B. Schofield would later serve as his Gen. J.M. Schofield's aide during the Indian Wars from 1878-1885. After rising to the rank of Captain during the Spanish-American War, he died of a heart attack in Matanzas, Cuba in 1901 and was also buried at Arlington National Cemetery. While Gen. John Schofield was in charge of Military District No. 1 in Virginia, his brother Elisha McAllister Schofield (1835-1882) was the assessor for the City of Richmond, Virginia and was among many killed on April 26, 1870 as a result of the collapse of the balcony during a session of the Virginia Court of Appeals. His son in law, Brig. Gen. Avery Delano Andrews and his wife Mary Campbell Schofield Andrews are also buried at Arlington National Cemetery.

Question:
Jesse Donald Knotts was born in Morgantown, West Virginia, the youngest of four sons born to farmer William Jesse Knotts and his wife, Elsie Luzetta Knotts (nee Moore). His parents were married in Spraggs, Pennsylvania. His English paternal ancestors immigrated to America in the 17th century, originally settling in Queen Anne's County, Maryland. Knotts' brothers were named Willis, William, and Ralph.
In 1986, Don Knotts reunited with Andy Griffith in the made-for-television film Return to Mayberry, again reprising his Barney Fife role. In early 1987, Knotts joined the cast of the first-run syndication comedy What a Country!, playing Principal Bud McPherson for the series' remaining 13 episodes. The sitcom was produced by Martin Rips and Joseph Staretski, who had previously worked on Three's Company. In 1988, Knotts joined Andy Griffith in another show, playing the recurring role of pesky neighbor Les Calhoun on Matlock until 1992.  After that, Knotts's roles were sporadic, including a cameo appearance in the film Big Bully (1996) as the principal of the high school. In 1998, Knotts played a small but pivotal role as a mysterious TV repairman in Pleasantville. That year, his home town of Morgantown, West Virginia, changed the name of the street formerly known as South University Avenue (U.S. Route 119) to Don Knotts Boulevard on "Don Knotts Day." Also that day, in honor of Knotts's role as Barney Fife, he was named an honorary deputy sheriff with the Monongalia County Sheriff's Department.  Knotts was recognized in 2000 with a star on the Hollywood Walk of Fame. He continued to act on stage, but much of his film and television work after 2000 was as voice talent. In Ghost World (2001) Enid (Thora Birch) is asked why she painted a portrait of Don Knotts. She replies, "I just like Don Knotts." The portrait in the film may be the last visual image of Knotts in a motion picture. In 2002, he appeared again with Scooby-Doo in the video game Scooby-Doo! Night of 100 Frights. (Knotts also spoofed his appearances on that show in various promotions for Cartoon Network and in a parody on Robot Chicken, where he was teamed with Phyllis Diller). In 2003, Knotts teamed up with Tim Conway again to provide voices for the direct-to-video children's series Hermie and Friends, which continued until his death. In 2005, he was the voice of Mayor Turkey Lurkey in Chicken Little (2005), his first Disney movie since 1979. On September 12, 2003, Knotts was in Kansas City in a stage version of On Golden Pond when he received a call from John Ritter's family telling him that his former Three's Company co-star had died of an aortic dissection that day. Knotts and his co-stars attended the funeral four days later. Knotts had appeared with Ritter one final time in a cameo on 8 Simple Rules for Dating My Teenage Daughter. It was an episode that paid homage to their earlier television series. Knotts was the last Three's Company star to work with Ritter.  During this period of time, macular degeneration in both eyes caused the otherwise robust Knotts to become virtually blind. His live appearances on television were few. In 2005, Knotts parodied his Ralph Furley character while playing a Paul Young variation in a Desperate Housewives sketch on The 3rd Annual TV Land Awards. He parodied that part one final time, "Stone Cold Crazy", an episode of the sitcom That '70s Show. In the show, Knotts played Fez and Jackie's new landlord. This was his last live-action television appearance. His final role was in Air Buddies (a 2006 direct-to-video sequel to Air Bud), voicing the sheriff's deputy dog, Sniffer.
