What a suprise. Issac and lucinda are my great grandparents also. What kind of info do you need on Issac? There is a book in the process of being printed on the Allen history and I can send you his email address if you email me. Where are you from and your last name. The Allens are hard to track their history but I am working on it and will help with anything that I can Elsie Ruth's brother Hosea is my grandfather. Will be good to hear from you.
