Question: How many wives did Katherine's maternal grandfather have? Passage:Lady Katherine Neville was born in 1442, one of the ten children and the fifth eldest daughter of Richard Neville, 5th Earl of Salisbury and Alice Montacute, suo jure 5th Countess of Salisbury. Her mother was the only child and heiress of Thomas Montacute, 4th Earl of Salisbury by his first wife Lady Eleanor Holland. Katherine's eldest brother was Richard Neville, 16th Earl of Warwick, 6th Earl of Salisbury, also known as "Warwick the Kingmaker". He was the most important and influential peer in the realm, and one of the principal protagonists in the Wars of the Roses. Her aunt, Cecily Neville, Duchess of York, mother of future kings and Katherine's first cousins, Edward IV and Richard III, was another key figure in the dynastic civil wars that dominated most of the latter half of 15th century England. Her niece, Anne Neville (youngest daughter of the "Kingmaker") would become Queen of England as the consort of Richard III; Katherine's sister Alice, Baroness FitzHugh, and her other niece, Elizabeth FitzHugh, were personally selected as Anne's chief ladies-in-waiting. Her paternal grandparents were Ralph Neville, 1st Earl of Westmorland and Joan Beaufort, Countess of Westmoreland, a daughter of John of Gaunt by his third wife, Katherine de Roët, making her a direct descendant of Edward III.

question:
Question: Who was the founder of the railroad? Passage:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.

Question: What state was the university Davidson got his M.A. from located in? Passage:Levette J. Davidson was a nationally acclaimed expert in folklore, especially that of Colorado and the West. He was born in Eureka, Illinois May 16, 1894, one of four children. Because his grand uncle was past-President of Eureka College, a Christian seminary, Davidson was reared in the school's shadow with the option of becoming either a teacher or a preacher. He chose teaching and was awarded his B.A. from Eureka in 1915. A year later he received his A.M. degree from the University of Illinois where he received Phi Beta Kappa honors. In 1917 he earned his M.A. in social science and history at Harvard University. __During World War I, he served with the Tenth Infantry of the Forty-Sixth Division and also served as an army sergeant in Intelligence. Davidson and his wife Mary, also a graduate of Eureka, were married in 1918. At the end of the war, Davidson simultaneously taught and studied at the University of Michigan where he earned a Ph.D. in languages and literatures in 1922. He arrived in Denver later that year and began teaching at the University of Denver. Before arriving in Colorado, his academic specialty was eighteenth century England. Once in Denver, he realized that Western literature and folklore would be his life work. Davidson taught at the University of Denver until his death in 1957. His course topics ranged from studies of Shakespeare and other English literature, to folklore in the West. He began teaching news writing and eventually founded the journalism department at the University as well as the board of publications and the press club. He was the first faculty member elected to serve as president of the University Senate. In 1940 he became head of the English Department and from March to August 1953 he served as interim Chancellor. At the time of assuming his post, he remarked: There is hardly an organization on campus that I have not been connected with at one time or another. Davidson was named University Lecturer for 1956. Davidson was a director of the Colorado State Historical Society, the Modern Languages Association, the American Folklore Society, and the American Dialect Society. He was a charter member of the Denver Posse of the Westerners, an organization devoted to western folklore. In spare moments, Davidson conducted research, wrote outlines for plays, and authored a large number of articles. He contributed to a wide range of magazines from Western American to Shakespeare Quarterly. Additionally, Davidson authored several books on folklore. The most widely recognized is Rocky Mountain Tales, which presents regional folklore as well as true accounts of early events in the area. Levette Davidson died May 14, 1957.
