I have posted an on-line Album of pictures from the Knapp/Sage Family Pioneer Cemetery on Clarkson-Parma Townline Road, Parma, New York on my personal website at:
www.geocities.com/mr5by5/sage_cemetery/index.html

Included are markers for several members of mid-19th Century Piers family - please check it out and let me know if you can ID any of the numbered headstones and/or correct my transcription of any others!
