This series consists of correspondence sent to Edith Ogden Harrison, Harrison's wife. Most of the letters are personal in nature and fairly short. Some simply seek to arrange a time for a visit, while others are about the health and current activities of the sender and his or her family. The letters that she received from William Preston Harrison, Harrison's brother, are more numerous and of greater length. Most of these letters were written by William Preston Harrison while he was in Europe and tell of his travels.
