Commodore Byron McCandless was a longtime U.S. Navy officer who was awarded the Navy Cross during World War I and the Legion of Merit during World War II. He was also prominent in the field of vexillology, and helped design two separate versions of the flag of the president of the United States. He was the father of Bruce McCandless, also a naval officer, and the grandfather of NASA astronaut Bruce McCandless II. Commodore McCandless was later promoted to the rank of Rear Admiral on the retired list.

The McCanles Gang was an alleged outlaw gang active in the early 1860s that was accused of train robbery, bank robbery, cattle rustling, horse theft, and murder. On July 12, 1861, some of its supposed members, including alleged leader David Colbert McCanles, were killed by "Wild Bill" Hickok during a confrontation at a Pony Express station in the Nebraska Territory. The incident was among the earliest to frame Hickok's later reputation as a legendary gunfighter.
