This three-story house was built by the owners of the largest and most successful quarry in Port Deposit from the 1830s to 1914. The Queen Anne house has granite first and second floors with frame on the third and incorporates a smaller frame house at the rear from the 1840s. John McClenahan also built the large semidetached house at 60–62 S. Main in the 1880s, with one side for his son and the other for his daughter. This house is granite at its raised basement and first floor and frame covered with fashionable clapboards and shingles on the second and third floors.
