I know she has been mentioned before but if you are still looking for a fabulous program for your library, I absolutely recommend Michigan author Teresa Irish who wrote the book A Thousand Letters Home and presents The Journey of the Letters to libraries all over, especially Michigan.  I can't say enough about her to convince you but there is a little something for everyone.  A love story, historical aspects, military, genealogy, family, humor and music.  She had all of us laughing, crying, singing and reminiscing.  Her program will keep you entertained the entire time with her stories and tons of photos from times past. She is completely affordable and well worth it.  Below is her contact info and website for more information, she really will get right back with you when you email her.  You can even search her events  on the website to see when she will be close to your area.  Those who have heard her speak, don't you agree?  Completely enjoyable.
