Ben Lilly: Benjamin Vernon Lilly or Ben Lilly (1856 – December 17, 1936), nicknamed Ol' Lilly, was a notorious big game hunter, houndsman and mountain man of the late American Old West.  He remains famous for hunting down large numbers of grizzly, cougars and black bears.  A mix between a transcendentalist spirit and an ardent Christian, he is described as an unfathomable Southern wild character.  He was a stern practitioner of simple living and outdoor freedom, roamed and hunted from Louisiana to Arizona and from Idaho to as far south as Chihuahua and Durango, Mexico, and was a subject of American folktales.  He guided oiler W. H. McFadden and President Theodore Roosevelt in hunting expeditions, whom he intrigued and who wrote about him.  He was arguably the most prolific hunter of apex predators in the history of North American hunting and also the last active mountain man of the historical American Southwest.  He was not a conservationist but made important contributions of fauna specimens and naturalistic observations to American institutions and museums.  He was a contradictory character and his exploits have been consistently exaggerated to folktale proportions, and most records are oral, bona-fide, Americana transcripts.

Louis Vasquez: Pierre Luis Vasquez (October 3, 1798 – September 5, 1868) was a mountain man and trader.  He was born and raised at St. Louis, Missouri.  Pierre Luis Vasquez was the son of Benito Vasquez and Marie-Julie Papin (daughter of Pierre Papin & Catherine Guichard.  Benito was born in Galicia, Spain in 1738 son of Francisco Vasquez and Marie de La Ponte.  Many historians write that Pierre Luis was a Mexican-American but he was of French and Spanish (European) descent.  In 1823, he became a fur man, receiving his first license to trade with the Pawnee.  By the early 1830s he had shifted his operations to the mountains, a popular and active mountain man and trader.  Pierre Luis was nicknamed "Old Vaskiss" by other Mountain men.  Vasquez became a partner of Andrew Sublette, perhaps in 1834, returned to St. Louis in 1835, and went back to trade on the South Platte that winter and built Fort Vasquez that year after obtaining a trading license in St. Louis, Missouri, from William Clark, the Superintendent of Indian Affairs.  He traveled back and forth between the mountains and St. Louis almost yearly, his reputation growing.  Unable to turn a profit, they sold Fort Vasquez to Lock and Randolph in 1840 who subsequently went bankrupt and abandoned the structures in 1842.  Due to the bankruptcy, Luis Vasquez and Andrew Sublette could not collect the sum owed to them for the sale.  Vasquez then became associated with Jim Bridger.  By 1843 they had built Fort Bridger on Blacks Fork of the Green River, which became as much an emigrant station as trading post.  At St. Louis in 1846 Vasquez married a widow, Mrs. Narcissa Land Ashcraft and took his new family, her son and daughter, to Fort Bridger in Wyoming.  Vasquez opened a store at Salt Lake City in 1855.  He and Bridger sold their fort in 1858, but Vasquez already had retired to Missouri.  He died at his Westport home, and was buried at St. Mary's Church cemetery.
