Ogilvie was called Groundhouse until January 1, 1900, when the community was renamed for Oric Ogilvie Whited, a local landowner. The town incorporated in 1902.
One of Ogilvie's founding fathers was John Bragg, who started a combined lumberyard and general mercantile in 1898. In 1900 he built a new two-story general mercantile-only store, which also featured one of the area's first soda fountains. The Bragg General Store, as it was known then, also featured a connected storage warehouse, and the second floor was used as a public hall where the "Modern Woodsmen Lodge of Ogilvie" held dances every Saturday night. In 1902 the Bragg General Store was sold to E.F. Ohman, while John Bragg started another lumberyard. Today the Bragg building is one of Ogilvie's oldest.
