Thanks so much for writing. I don't know of a Caroline Allison but I don't know the names of the later Allisons of Dade Co., GA. Have you looked in Jackson Co., AL for the Allisons because they settled down there very early? If you find out more, let me know. Where in Marion Co., or Dade Co. did your William live? My husband has William J. Smith born 1847 GA who married Sarah Head and they lived in the Battle Creek area. Thanks again. Marilyn
