Isaac D. Everett was born in 1830 to Adam and Mary (Wolverton) Everett. In 1862, he married Lavinia Nettleton, who was fondly known as Fanny. He was the brother in law of Leonard B. Johnson, the owner of Johnson’s Island at the time.
In the 1867 Sandusky City Directory, Mr. Everett was in a partnership with Andrew Zerbe and E. and F. Nicolai in a dry goods business on Water Street between Columbus Avenue and Jackson Street.
By 1876, Isaac and his son had their own store on Columbus Avenue. They sold china, glass and queensware, which was a cream-colored earthenware.
An advertisement which appeared in the April 16, 1890 issue of the Sandusky Register announced the opening of a new store, run by Isaac D. Everett and his son Lu. The store sold groceries, fruits, and candies, and was located at 234 Columbus Avenue.
