Xavier Chapter was named in honor of John Sevier, who was a member of the ancient and honorable Navarrese family of Xavier (anglicized Sevier). He was the first child of Valentine Sevier II and Joanna Goade and was born September 23, 1745 in Augusta County, Virginia. He died September 24, 1815 on the east bank of the Tallapoosa River, near Fort Decatur, Alabama. He was buried there, but later his body was removed to the Court House Square in Knoxville, Tennessee. He was married twice – first in 1761 to Sarah Hawkins and second, August 14, 1780 to Catherine (Bonnie Kate) Sherrill.

John Sevier served in the Colonial wars, as well as in the Revolution. He led the Etowah Campaign against the Creek and Cherokee Indians, which ended in the Battle of Etowah on October 17, 1783 (at what is now Rome, Georgia) and the death of the Creek leader, The King Fisher. The Etowah Campaign was the last military service rendered by John Sevier and the only one for which he ever received compensation from the Government.
