This is my first foray into Waukesha Co., WI and I would appreciate any guidance. I have in the 1900 Eagle, Waukesha Co., WI federal census, a grandfather, Daniel OLVER, born June 1821 in England.He lived with George and Mary CUMMINGS. Daniel Olver has been very elusive in the US.He left his wife and children and went to Savannah, GA.His stated immigration date doesn't match but perhaps the family wasn't sure when he left the old country. He was 78 years old on this census, so chances are very good that he died before the 1910 census, probably in Eagle and is buried there. Can someone guide me in researching this area?
