[2] Medor and Joseph Trombley, both French-Canadian fur traders, settled in the Saginaw Valley in the early 1830s and purchased large tracts of land along the Saginaw River between what is now Twenty-third Street and Cass Avenue in Bay City.

The house at that time was located on the east side of the river, at what is now 114-118 Webster Street.

The Trombleys used the building as a house, as a place to conduct their trading business, and as an inn of sorts.

[3] After Ellen McCormick's death in 1854, Medor Trombley again took ownership of the house, and held onto it until 1899.

[4] During this time, the house also served as an inn or hotel, with out-of-town businessmen staying there.

[4] In 1981, the owner of the Trombley House wished to clear the site to make a parking lot for the adjacent business.

Rather than being demolished, the house was ferried to the present location in Veterans Memorial Park on the other side of the Saginaw River.
