The register for the Immaculate Conception Catholic Church collection was compiled by Nell-Garwood MacEachern in April, 2001. No restrictions apply to the remainder of this collection. The period of the American Civil War saw the Catholic population of Toledo grow at about the same pace as the general population. The Irish immigrants in particular, who had come to build first the Miami and Erie Canal and then the railroads, swelled the ranks of St. Patrick's Church. In 1867, Father Edward Hannin petitioned Bishop Rappe to divide the territory and establish a new parish bounded by Swan Creek and the Maumee River.
