The community of St. Patrick was founded around St. Patrick's Catholic Church, which was established in the area in 1862. Unlike most parts of the heavily Catholic plains of far western Ohio, which were settled primarily by Germans, the population of St. Patrick was predominantly Irish.[4] A post office was established in the community on 22 September 1893; when it was discontinued on 30 June 1904, mail was processed through the post office at Swanders.[5]
Today, St. Patrick is a very small community, due in part to a general decline in the rural population;[4] although the church was placed on the National Register of Historic Places in 1979,[6] it has since closed and been destroyed.[7] A memorial sits at the site of the church.[8]
