In 1797 the Town of Willington granted permission for Gen./Dr. Miner Grant to build a store to the southeast of the town green. It was built as a one-and-a-half story cape with its gable end facing the street. The store was in operation until the period of the Civil War. It was then converted into a residence and significantly altered. The original store entrance was located in the center of the gable end, where there is now a chimney. By 1801, Dr. Miner Grant’s son, Miner Grant, Jr., was working as a store clerk for Dr. Samuel Willard of Stafford. An accidental explosion on December 23, 1801 led to a fire that destroyed the store. Willard and Grant escaped, but another clerk, Augustus Miller, was killed. The store was rebuilt the following year and the business was acquired by Miner Grant, Sr., who was setting his son up in business. In 1806, Miner Grant, Jr. took over the Stafford store, which was moved to Old Sturbridge Village in 1938. His father’s earlier store, now a house, remains in its original location at 242 Tolland Turnpike in Willington.
