This Caroline Combs is my ancestor and she had a brother named Harrison, who had a son Joe. This is the information that I have. I know the dates don't exactly match, but have found in my research that what we think we know as fact, sometimes isn't exactly correct. Let me know if you think that these people might be from your family!
