I was looking over the Allen forum and the “NC” caught my eye, then the “Alamance co.” My family is of the Alamance County/Cane Creek/Snow Camp line and I am sure that my GG grandfather was called Joseph Allen, so this would be about the middle to early 19th century. I do not know the dates exactly but I have them in the Allen Family book by Lester Allen. http://www.wisecomp.com/ccl/BooksLofC.htmhttp://www.wisecomp.com/ccl/BooksLofC.htm Try that book then and I am sure you will find him in there. It lists 1000s of Allens. That is the book I have.
Do write me back and tell me what you find then. I hope that helped. I have other references for that area and family as well. Tell me how you are connected and I can look them up. Again, I think that will solve your enquiry.
