Wells was born on December 5, 1871, in Salt Lake City, Utah Territory, as the son of Daniel H. Wells and Martha Givens Harris. His father was a mayor of Salt Lake City and an apostle of the Church of Jesus Christ of Latter-day Saints (LDS). Briant had a total of thirty-seven siblings due to his father's LDS religion, which allowed Polygamy. Some of his siblings had also distinguished careers later: Heber M. Wells, first Governor of the State of Utah; Elizabeth Wells Cannon, a prominent women's suffragist or Rulon S. Wells, a Utah politician. His father was also head of the Nauvoo Legion (the name given to the predecessor of the Utah National Guard during the early period of Utah Territory).^[3][1][2]

In May 1890, Wells received an appointment to the United States Military Academy at West Point, New York, where he graduated four years later with Bachelor of Science degree.
