Washington's six-point plan included impartial justice toward Indians; regulated buying of Indian lands; promotion of commerce; promotion of experiments to civilize or improve Indian society; presidential authority to give presents; and punishing those who violated Indian rights. The government appointed agents, such as Benjamin Hawkins, to live among the Indians and to teach them through example and instruction, how to live like whites. While living among the Choctaw for nearly 30 years, Hawkins married Lavinia Downs, a Choctaw woman. As the people had a matrilineal system of property and hereditary leadership, their children were born into the mother's clan and gained their status from her people. In the late eighteenth and early nineteenth century, a number of Scots-Irish traders lived among the Choctaw and married high-status women. Choctaw chiefs saw these as strategic alliances to build stronger relationships with the Americans in a changing environment that influenced ideas of capital and property. The children of such marriages were Choctaw, first and foremost. Some of the sons were educated in Anglo-American schools and became important interpreters and negotiators for Choctaw-US relations.
