her death, he married again, to a woman named Priscilla. He had ten children (these were probably Greenwood's brothers and sisters, not his children): William, Benjamin, Basil, Clarissa, Forbis, Jackson, Emily, and three other daughters. According to other records his children included: Jane (married William Spring), John Donley LeFlore, Jackson LeFlore, and Greenwood LeFlore by Rosa Donly; and Rebecca (married James Clark Harris) and Clarissa (married Chief Edmond Aaron McCurtain) by Rosa's sister Priscilla Donly. Advocate of civilization While LeFlore was not said to be popular among the full-blood tribal men, he became powerful and influential within the tribe at an early age, largely because of his mother's clan and maternal uncle's position and his own skills. With other leaders, he struggled to resist European-American encroachment while adapting to some of the new ways and the increasing pressure from the United States government in support of removal. When Leflore was 22, he became a chief of the western division of the Choctaw Nation, when it was still in Mississippi.

Removal or U.S. citizenship Despite being recognized as one of the "Five Civilized Tribes", the Choctaw were under pressure from encroaching European-American settlers. The settlers kept entering the Choctaw Nation lands in great numbers. The US government wanted to remove the Choctaw to lands west of the Mississippi River. With the election of Andrew Jackson as president in 1828, who supported Indian removal, many Choctaw claimed that removal was inevitable. They concluded they could not give armed resistance. After passage of the Indian Removal Act of 1830, the chiefs of the western and eastern districts resigned, and on March 15, 1830, the council elected LeFlore as principal chief, the first time that power had been so centralized among the Choctaw. He drafted a treaty which he sent to Washington, to try to secure the best terms for the Choctaw. United States representatives came out to the Choctaw for a treaty council, where LeFlore used his formidable personal political capital and
