Like many other larger community areas in Chicago, Ashburn includes numerous neighborhoods, one of which is actually named after the community area. The neighborhood of Ashburn, which is only about one square mile in size, "was predominantly Irish-Catholic until the 1990s," and until that point was commonly referred to as "St. Denis." St. Denis is the name of the church and parish that residents belong to, and thoughout Chicago's history, referring to the area by it's parish name is a common theme on the city's southwest side. Residents of the surrounding neighborhoods in the Ashburn community area also are referred to by the church rather than the official name; Scottsdale, on the western side, is often referred to as St. Bede, while Wrightwood, to the east, is commonly called St. Thomas More (or "Tommy More").
