Ann's children were all born into their mother's clan. They were reared by their mothers and their maternal male relatives following Muscogee cultural practices, and they gained their social status from their mother's people. Ann McQueen was also mixed-race Muscogee Creek; her father, James McQueen, was Scottish. Ann was probably the sister or aunt of Peter McQueen, a prominent Muscogee leader and warrior. Like his mother, Billy Powell was raised in the Muscogee Creek confederacy. Billy Powell's maternal grandfather, James McQueen, was a ship-jumping Scottish sailor who in 1716 became the first recorded white person to trade with the Muscogee Creek Confederacy in Alabama. He stayed in the area as a fur trader and married into a Muscogee family, becoming closely involved with these people. He was buried in 1811 at the Indian cemetery in Franklin, Alabama, near a Methodist missionary church for the Muscogee. In 1814, after the Red Stick Muscogee Creeks were defeated by United States forces, Polly took Osceola and moved with other Muscogee refugees from Alabama to Florida, where they joined the Seminole. In adulthood, as part of the Seminole, Powell was given his name Osceola ( or ). This is an anglicized form of the Creek Asi-yahola (pronounced ); the combination of asi, the ceremonial black drink made from the yaupon holly, and yahola, meaning "shout" or "shouter". In 1821, the United States acquired Florida from Spain, and more European-American settlers started moving in, encroaching on the Seminoles' territory. After early military skirmishes and the signing of the 1823 Treaty of Moultrie Creek, by which the US seized the northern Seminole lands, Osceola and his family moved with the Seminole deeper into the unpopulated wilds of central and southern Florida. As an adult, Osceola took two wives, as did some other high-ranking Muscogee and Seminole leaders. With them, he had at least five children. One of his wives was black, and Osceola fiercely opposed the enslavement of free people. Lt. John T. Sprague mentions in his 1848 history The Florida War that Osceola had a wife named "Che-cho-ter" (Morning Dew), who bore him four children. 1830s resistance and war leader Through the 1820s and the turn of the decade, American settlers continued pressuring the US government to remove the Seminole from Florida to make way for their desired agricultural development. In 1832, a few Seminole chiefs signed the Treaty of Payne's Landing, by which they
