The original one-and-one-half story farmhouse was built in the 1750’s.  This austere house was expanded in four stages, the last being the addition of a second story in 1860 by Alexander Gardiner for his mother Fannie, who was living here at the time.

The last generation to live in the house were  Alice (1896-1985), Zella (1898-1905), and the twins Harold (1902-1982) and Herbert (1902-2002).  Herbert and Harold were born in the farmhouse. They lived here their entire lives with their sister Alice and never married, and never lived anywhere else.  Herbert Gardiner, the last family member to live here, bequeathed the property to the Greenlawn-Centerport Historical Association.  It was his wish to name it in memory of his father John. The farm, which is on the National Register of Historic Places is being maintained as a museum complex with a working farm to highlight early farm life in the community.                                                                                                                                                                                                           Alexander S.  Gardiner, a descendant of the Gardiner family of the East End of Long Island,  was born in the Huntington area March 4, 1835.  His ambitious character was evident at an early age.  As a boy, he was enamored with tools of all kinds and had a small blacksmith shop that he expanded on as he got older, gradually learning to make and repair the  parts of all farm implements.

Alexander became quite an entrepreneur and operated a large cider mill, sawmill, a brickyard, a gristmill and an icehouse.  He sold the latest farm machinery, wagons, and later had an automobile dealership.  Over the years he acquired 600 acres of farmland and kept expanding on his ventures.  He had interests in a cannery, sailing vessels, the Huntington Station Fair Grounds, and he pioneered the chicory crop on Long Island.  Alexander Gardiner was considered one of the leading farmers in Huntington and  he earned his title as Greenlawn’s “Pickle Pioneer” ” by proposing that local farmers try growing pickles.  He developed  “Green Prolific Pickle Seeds”, built processing plants, and established a freight depot along the railroad tracks. Greenlawn soon had a thriving Pickle Industry.l .

On November 13, 1842, Alexander Smith and his wife Rebecca were brutally murdered in the front parlor of their home, apparently while enjoying their evening tea. The couple was well respected in the community, and their only child, Fanny, had married Joel Gardiner from another prominent Greenlawn family. It was believed that the motive for the terrible crime was theft.  At the time of the murders, the only person also known to have been in the house with the Smiths was Antoine Geisler, a recent immigrant from Germany who had been working as a farmhand for the Smiths for two weeks prior to the occurrence. Mr. Geisler was nowhere to be found.  A $500. reward was posted- a princely sum in those days- he was found in a barn and captured near Port Jefferson the following Tuesday and brought to trial in Riverhead in May. As Mr.Keisler, a German immigrant was illiterate and only spoke a bit of English, the trial was delayed until an interpreter could be found. He was found guilty and hung on June 5th 1843. The ongoing effort to restore the Farm and open it to the public represents the communities' dedication to the preservation of local history.  Such an effort would not be successful without the continued support on the community and the help of volunteers
