Bragg grew up in Washington, D.C. with his parents, Robert Elton Bragg (1866-1944), who had procured a U.S. Civil Service position there, and Caroline (Chappuis) Bragg (1859-1934). He had two brothers, James Elton Bragg and John Harrison Bragg. His father was employed by the U.S. Printing Office. However, in the 1972 Edition of the Bragg Apple Cider Vinegar System booklet, at page 12, and in later editions, Bragg claimed both that his father was "a splendid farmer" and that "I am the oldest of 16 children".
