The are no other nearby structures that appear on the 1877 map, but the Sanborn Insurance survey of Chesaning from 1893 does show an ice house and storage building close to this location, which is why I am going to tentatively identify this location as Trefry’s grocery store.
The next building was another blacksmith shop (3), this one belonging to to Edwin Hewitt (1839-1918). Edwin was born in Grand Blanc, and came to Chesaning sometime around 1871.
Then we have the saloon (4) of Henley Cutting. The photo above shows a comparatively large, two story building, so it must have served some additional function. Other sources list Henley as operating a hotel, livery, restaurant and billiard hall.
The grocery store (5) was owned by Daniel Cummins (1824-1899).
Daniel Cummins was born at Newstead, in New York state, and spent most of his life there as a farmer. He had attempted to enlist in the Union Army, during the Civil War, but was rejected on account of an unspecified physical disability.
He came to the Chesaning area in 1869, where he continued his previous occupation as a farmer. He then became active in the manufacture of hoops, before eventually opening a mercantile store.
Llewellyn Homer (1850-1906) owned the billiard hall & restaurant (6), which was also listed as a saloon in other sources. Llewellyn is elsewhere identified as the proprietor of a meat market, so this location may have served that purpose as well.
Llewellyn was born in Pennsylvania, and came to Chesaning with his widowed father in the early 1860s. He later enlisted in the Union Army at the age of only fourteen and served with the 29th Michigan Infantry until the end of war.
