Samuel Langhorne Clemens was born in Florida, Missouri, on November 30, 1835, to John Marshall Clemens, (August 11, 1798 – March 24, 1847), a Virginian by birth, and Jane Lampton Clemens (June 18, 1803 – October 27, 1890) of Missouri.
Clemens came from St. Louis on the packet Keokuk in 1854, and lived in Muscatine during part of the summer of 1855. The Muscatine newspaper published eight stories which amounted to almost 6,000 words.
He was the sixth of seven children but only three of his siblings survived childhood: his brother Orion (July 17, 1825 – December 11, 1897); Henry, who died in a riverboat explosion (July 13, 1838 – June 21, 1858); and Pamela (September 19, 1827 – August 31, 1904). His sister Margaret (May 31, 1830 – August 17, 1839) died when he was three, and his brother Benjamin (June 8, 1832 – May 12, 1842) died three years later. Another brother, Pleasant (1828–1829), died at six months. Twain was born two weeks after the closest approach to Earth of Halley's Comet.
Twain joined Orion, who in 1861 became secretary to James W. Nye, the governor of Nevada Territory, and headed west. Twain and his brother traveled more than two weeks on a stagecoach across the Great Plains and the Rocky Mountains, visiting the Mormon community in Salt Lake City. The experiences inspired Roughing It and provided material for The Celebrated Jumping Frog of Calaveras County. Twain's journey ended in the silver-mining town of Virginia City, Nevada, where he became a miner. Twain failed as a miner and worked at a Virginia City newspaper, the Territorial Enterprise. Here he first used his pen name. On February 3, 1863, he signed a humorous travel account "Letter From Carson – re: Joe Goodman; party at Gov. Johnson's; music" with "Mark Twain."
Twain moved to San Francisco, California in 1864, still as a journalist. He met writers such as Bret Harte, Artemus Ward, and Dan D equille. The young poet Ina Cool brith may have romanced him.
