Hawthorne is an unincorporated hamlet inside the Town of Mount Pleasant. It was once known as Hammond’s Mills as a part of the Philipsburgh estate, which was owned by Frederick Philipse. The village was renamed Unionville after the Revolutionary War. The hamlet consisted mostly of farmers. The Reformed Chruch of Unionville (Hawthorne Reformed Church) was built in 1818. In 1847, a one-room school house was built. A railroad station was built here in 1847, and a post office established in 1851.
The village was finally named Hawthorne in honor of Rose Hawthorne, the founder of the Rosary Hill Home, where patients suffering from incurable cancer were cared for.
