Question:  Mabee House is part of the society that was established on what date?

The Wilbor House is a historic house museum at 548 West Main Road in Little Compton, Rhode Island, and currently serves as the headquarters of the Little Compton Historical Society.  The property includes eight buildings of historical significance, six of which were part of the Wilbor farmstead, a complex that was used for farming between 1690 (when the house was built) and 1955, when the property was acquired by the historical society.  The house is a 2-1/2 story wood frame structure, whose oldest portion was probably a stone ender built by Samuel Wilbor, and whose western half was added c. 1740, giving it a Georgian appearance.  The five farm outbuildings all date to the 19th century. <SEP> The Mabee Farm Historic Site, part of the Schenectady County Historical Society, is the oldest house still standing in the Mohawk Valley.  It is located in the town of Rotterdam, New York, in the hamlet of Rotterdam Junction, New York, along New York State Highway 5S, about six miles (10 km) west of the city of Schenectady. <SEP>  The Society is an independent not-for-profit corporation, not a unit of government. The Schenectady County Historical Society, located in Schenectady, New York, was established on July 14, 1905, under the Membership Corporation Laws of the State of New York.  Its stated mission as embodied in its constitution was, and remains, “to promote and encourage original historical research; to disseminate a greater knowledge of the history of the State of New York and particularly of Schenectady County; to gather, preserve, display, and make available for study artifacts, books, manuscripts, papers, photographs and other records and materials relating to the early and current history of Schenectady County, New York and of the surrounding area; to encourage the suitable marking of places of historic interest; to acquire by purchase, gifts, devise, or otherwise the title to or the custody and control of historic sites and structures.” <SEP> Daniel Nelson House and Barn, also known as the Nelson Pioneer Farm and Museum, are historic buildings located north of Oskaloosa, Iowa, United States.  Daniel and Margaret Nelson settled here in 1844, a year after this part of Iowa was opened to settlement by the U.S. Government.  Their first home was a log structure, non-extant, located northeast of the present house.  The present house is a two-story, brick structure with a gable roof.  The wooden porches on the front and back of the house date from 1898 to 1900.  The large barn measures 61 by , and was built in 1856.  It is composed of board and batten construction from oak that was milled on the site.  It was used largely as a granary, rather than a shelter for farm animals.  Three other buildings included in the historic designation include the summer kitchen, woodshed, and a small outdoor privy.  The dates of construction for the three frame buildings is unknown.  The farm remained in the Nelson family until 1941 when it was abandoned with most of the original furnishings intact.  The property was donated to the Mahaska County Historical Society, which now operates it as a museum.  Other historic buildings have been moved to this location over the years.  It was listed on the National Register of Historic Places in 1974.
