Bernice,

I know you are celebrating Rev John right now, but I think I found something on Isaac. If this document is correct, it appears that Isaac and Chappo may have lived in Lebanon, PA in 1911. I found it in the city directory for 1911 in Lebanon, PA. It list Isaac McFadden, Mrs. Chappo and guess what, a Isaac Jr! I'm not sure if you have found this, but thought I would pass it along anyway! I found it at ancestry.com.
