[1] When the land around Grass Lake was opened up to European settlers in the 1830s, the plot where this building now stands was bought and sold multiple times.

Finally, in 1837, the parcel was sold to Daniel Walker, one of the area's first European inhabitants and the founder of Grass Lake village.

When Maria died in 1846, a parcel was split off for her son, William H. Walker, who was a local brick manufacturer and eventually established a drug business.

Walz remained in the house many years, renting rooms and raising her family, She eventually sold it to Archie and Myrta Coe.

Myrta Coe arranged to have the Grass Lake Area Historical Society purchase the home, to turn into a museum.
