Re:PAUL--I think you have the wrong town. To my knowledge there are no Market nor Water streets in Wash. They are in Belvidere at the traffic light. Don't know Paul - not in my family, but it seems to me I once heard the mansion was where the Food Mart is today, on the northwest corner. Warren Co. Hist. Soc may be able to help, or the Belvidere library. Good luck.
