The village was founded by Peter Lennon. He got the Grand Trunk Western Railroad routed through the settlement and a depot built there. He built a grain elevator, which was followed by other businesses. A post office was established in Clayton Township, Genesee County in July 1880 with Lennon as the first postmaster. The office was transferred to Shiawassee County in February 1889.
