This excellent example of the Pennsylvania farmhouse type was built by Dirck Jansen, one of the original settlers of Germantown, for his son John Johnson at the time of his marriage to Rachael Livezey. The work was begun in 1765 and completed in 1768, as indicated by a date stone in the peak of one of the gables. It was one of the largest and most substantial residences in the town and for that reason gave much concern to the Society of Friends of which the Johnsons were members. During the Battle of Germantown it was in the thick of the fight, and following the warning of an officer John Johnson and his entire family took refuge in the cellar. Bullet holes through three doors are still visible, also the damage done to the northwest wall by a cannon ball. The backyard fence, riddled with bullets, was removed in 1906 to the Museum of the Site and Relic Society at Vernon. Since the death of John Johnson in 1805, the house has passed through many hands, all descendants of the builder, however. During the Civil War it became a station of the "underground railway" for conducting fugitive slaves to Canada, and Mrs. Josiah Reeve, a great-great-granddaughter of the builder, used to tell how, when a child, she often wondered why so many colored people lived in the attic, staying only a day or so, when others would appear. Generally similar to the Johnson house is the old Green Tree Inn, Number 6019 Germantown Avenue, Germantown, erected in 1748. Its principal distinctions lie in the three small, plain dormers with segmental topped windows; the coved cornice; the elliptical carving in the pediment of the hood over the door; the enriched ovolo molding of the penthouse roof, consisting of a ball and disk in alternation, and the arched openings of the basement windows. In this building on December 6, 1759, then the home of Daniel Mackinett, the public school of Germantown, the Germantown Academy, was organized, its building being erected the following year. In Revolutionary times this old house was known as "Widow Mackinett's Tavern", and it was a famous resort for driving parties from the city. Many persons of note were entertained at the Green Tree Inn, and when La Fayette visited Germantown in 1825 it was the intention to tender him a dinner there. It was concluded, however, that the tavern could not accommodate the party, and a breakfast at Cliveden was given instead, to which reference has already been made.
