Reluctant to pursue her parents' career, the loss of financial support following the death of Louisa Lane Drew, caused Barrymore to give up her dream of becoming a concert pianist and instead earn a living on the stage. Barrymore's first Broadway role, alongside her uncle John Drew, Jr., was in "The Imprudent Young Couple" (1895). She soon found success, particularly after an invitation from William Gillette to appear on stage in his 1897 London production of "Secret Service".

His father, Henry Irving, cast her in "The Bells" (1897) and "Peter the Great" (1898).

Document 12: Los Angeles and Salt Lake Railroad: The Los Angeles and Salt Lake Railroad (reporting mark SLR) was a rail company that completed and operated a railway line between its namesake cities, via Las Vegas, Nevada. Incorporated in Utah in 1901 as the San Pedro, Los Angeles and Salt Lake Railroad, the line was largely the brainchild of William Andrews Clark, a Montana mining baron and United States Senator. Clark enlisted the help of Utah's U.S. Senator Thomas Kearns, mining magnate and newspaper man, to ensure the success of the line through Utah. Construction of the railroad's main line was completed in 1905. Company shareholders adopted the LA&SL name in 1916. The railway was also known by its official nickname, "The Salt Lake Route", and was sometimes informally referred to as "The Clark Road". The tracks are still in use by the modern Union Pacific Railroad, as the Caliente, Sharp, and Lynndyl Subdivisions.
Document 13: Marguerite McNulty: Marguerite McNulty (fl. c. 1920), who was regularly referred to in press as a “beauty”, was a U.S. stage actress. For decades in the early 20th century, she was cast in musical and other comedy productions on Broadway theatre, like the musical comedy "Fifty Fifty, Ltd." (1919) and the Broadway farce "The High Hatters" (1928). McNulty was also cast in a single silent film, 1925’s Ermine and Rhinestones. The daughter of an Armenian immigrant, McNulty’s true name was Katya Minasian, which came to light when it was nationally reported in late 1925 that she had filed suit against the scion William Andrews Clark III, the third grandson of the then very recently late railroad and mining magnate, financier, and U.S. Senator William A. Clark of Montana. McNulty’s claim against the younger Clark was for his allegedly having breached his promise to marry her. For several years prior, McNulty had a romantic relationship with Clark III, which his family worked hard to, eventually, successfully discourage. The enduring fame of “Marguerite McNulty” seems to arise solely from the wide national publicity given the lawsuit.
