DEDICATED: September 18, 2013

The marker commemorates pioneers Abraham and Mary Leatherman who settled on what is now Villa Olivia, in 1835. In addition to other businesses, the Leathermans managed an Inn where Hanover Township was organized on April 2, 1850 and for several years, was the location of the Township meetings.
