Also in Marquette county was part of what is now Waushara County.
This is a description of the area known as the Indian Lands in Green Lake, Marquette and Waushara Counties:
Source: Portrait and Biographical Album of Green Lake, Marquette and Waushara Counties, Wisconsin. Acme Publishing Co., Chicago, 1890, P203 October 18, 1848, the Government obtained title to the Menomonees' land within the State of Wisconsin, being the tract lying north and west of the Fox River between the Wolf and Wisconsin Rivers. It included nearly all of Waushara County, much of Marquette and some of Green lake County. This area has long been known as the "Indian Lands."
I do not know if the county has land ownership records from that far back - that they could look up by name.
Census listings were done in order by location. So someone who knows the area and some of the past history may be able to narrow the location down by the names listed near the ones you are interested in.
You could also search for the names in cemetery listings for those areas.
