Jim, You may want to check the LDS library. You can find it at http://www.familysearch.org/http://www.familysearch.org/. If they have it, check to see if it's on microfilm. If it's on mf you can "rent" it and have it sent to a center near you. I think I was told it costs about $2.50 a week. I'm not sure if they will make copies of the books they have or not. If you can't find it there or any place else try the Library of Congress. Historical societies sometimes have these books that are written about specific families try the one in the area your Allens came from in KY. I found all this out looking for a family book myself.
