I work for The Farmers' Museum and the Fenimore House Museum, both of which have separate charters and missions, etc - but, both of which are museums run under the auspices of the New York State Historical Association. NYSHA is a private non-profit organization which is devoted to the history of New York State. I don't know whether or not we are the kind of museums for which you are looking. Let me know if I can be of assistance, Katie Boardman Associate Director of Programs
