In the first years after the founding of the Colony of Georgia in 1733, these lands were known as the Grange or Cowpen plantation. About one mile east along the Savannah River stood the home of John Musgrove and his wife Mary, where they engaged in Indian trade, farming, and cattle raising. Mary Musgrove, famed in Georgia history for her services to James Edward Oglethorpe as an interpreter, was a half-breed whose Indian name was Cousaponakeesa and who was a niece of Old Brim, Emperor of the Creek Indians. The Musgrove house was a seat of hospitality, and important visitors entertained there included John Wesley. During the nineteenth century the lands became known as Colerain Plantation and were extensively cultivated as one of the largest rice plantations on the Savannah River. In ante-bellum days, near the former site of the Musgrove house, stood one of the finest mansions on the river, the home of James Potter, owner of Colerain. The erection in 1916 of the Savannah Sugar Refining Company plant on this property marked the beginning of the transition from Savannah's cotton and naval stores economy to that of a leading industrial seaport.
