The O’Hara Family of Prairie du Rocher Illinois
Henry O’Hara and his family, including his wife Margaret and ten children, relocated from Frederick County, Maryland, to Nelson County, Kentucky, in late 1811. After six years, they journeyed to Illinois, settling near Prairie du Rocher by 1818. Henry established the O’Hara Settlement and constructed a reliable clock, which passed through the family for generations. His son James, a pioneer in Southern Illinois, ran a successful farm and store. The family expanded, with notable members Charles and James R. O’Hara contributing to the community’s development.
