The Waukesha County Poor House and Farm was located in Vernon Township 1858-1905. It was then moved to Pewaukee Township, east of the northwest corner of CTH T on Northview Road. Just west of what is now the Waukesha County Fair Grounds.
It went by many names including: Waukesha Co. Home and Hospital, Waukesha Co. Poor Farm; Waukesha Co. Home; Waukesha Co. Insane Asylum; and Northview Home.
Waukesha County Museum and Historical Society has the records. They accept mail requests only and will do look ups for $10 each plus copying charges. Or you can look at the records yourself Tues-Sat 9:30-4:30.
