The area of present-day Catonsville was not inhabited by large numbers of Native Americans, rather serving as a hunting ground or a means of transit. However, Native American arrowheads found in the area signal a presence in small numbers. The Patapsco River itself, forming the southern boundary, bears a Native American name. They would have disappeared long before the first settlers encroached on the area, however.[5] The Native Americans had left behind a number of trails, some of which the earliest settlers adopted them for their own purposes. Rolling Road, for example, originated as a Native American trail, beginning from Elkridge Landing, and traveling north through present-day Catonsville—the road was repurposed as a "rolling road" used to roll hogsheads of tobacco, hence its current name. Another trail was the Old Frederick Road, now known regionally as Johnnycake Road, which began at a point along Gwynns Falls, and traveling northwest, forming what is now Catonsville's northern boundary. Another potential Native American trail is Old Frederick Road, branching off from the aforementioned road southwest toward Frederick Road near Ellicott City
