After Chief Alexis, a leader of the Chilcotin Indians. After the Chilcotin Massacre of 1864, Governor Seymour led a force into his territory. He described his meeting with Alexis thus: "....Chief Alexis and his men came on at the best pace of their horses, holding their muskets over their heads to show they came in peace. Having ascertained which was the Governor, he threw himself from his horse and at once approached me. He was dressed in a French uniform, such as one sees in pictures of Montcalm".
