1900 US Census
1900
Mathias and his family are listed in the 1900 US Census living in Sanborn, Ashland Co., Wisconsin, which is probably the location seen on the plat map in 1898. His youngest four daughters are still living with him at this time.
He is listed as a farmer, but he may also be doing the millwright work at the same time.
