ALLENBAUGH is one of the surnames in the 1928 Galion High School yearbook (Crawford County) that has been scanned and placed online at http://www.genealogybuff.com/oh/crawford/galion/webbbs_confi...
There is a list of alumni included that spans 1871 through 1927. Every page has been scanned, including the advertising. Even the ads have a lot of history. There are many autographs in the book. The book has all proper names OCR'd so that you can do a surname search in the searchbox at the top of the page.
Hope this helps.
