The community, as well as the township, were named for the little village of Admaston, Staffordshire, the native home of Sir Charles Bagot, second Governor General of the Province of Canada .

The community, as well as the township, took its name from Bagot's Bromley in Staffordshire, England, home of the Bagot family.

When the post office was established in 1854, Scottish settlers chose the name Douglas after a town in Lanarkshire, Scotland. The town of Douglas is the third of five chutes along the Bonnechere River. The others being Castleford, Renfrew, Fourth Chute and Eganville. The chutes were used for moving timber past rapids and waterfalls; Douglas had a 21-foot (3.4 m) waterfall over which log drivers had to shepherd their timber.

The community was most likely first settled in the 1830's by squatters on the land, as there was no land registry until the 1850's. The settlers, almost solely Irish Catholics, named the village after Croagh Patrick, in County Mayo, Ireland.
