According to the Morris County Heritage Commission:
"Ebenezer Stiles built the original section of this dwelling around 1752. His son, Ebenezer Jr. operated an iron works nearby. Lighthorsemen stayed at the house during the Revolution. When retired businessman Jonathan Roberts purchased the site in 1867, he attached to the original building an 1824 house moved from another location. He then altered and modernized both wings. The civic minded Roberts founded the Morris Plains Library Association in 1881. Today the house serves as the Morris Plains Public Library." [1]
