Founded in 1979, the museum has been the recipient of federal, state, county, and municipal, as well as corporate grants throughout its history as a public institution.

A new handicap accessible entrance with restrooms and a new addition with functioning exhibit space was completed in spring 2014 thanks to $150,000 grant administered by the New Jersey Historic Trust and matched by Piscataway Township. Piscataway Township partners with the Fellowship in caring for the historic site and has recently designated funds to repair the building as its commitment to cyclical mainteneance of all township properties.
