History


18th century

The first building on the Mount Clare property was built by John Henry Carroll, Charles Carroll's brother, (1723–1783), in 1754, and was probably eventually incorporated into the larger house. Charles inherited the property after John's death. The property consisted of 800 acres from the much larger Georgia Plantation, which had belonged to their father, Dr. Charles Carroll. Mount Clare overlooked the northwestern shore of Ridgely's Cove of the Middle Branch and Ferry Branch of the
