Hi Frank. I have seen the Ewan name in some of my gleanings, but not the Giberson. But, may I suggest this URL in Ancestry.com? (http://awt.ancestry.com/cgi-bin/igm.cgi
) It appears others have been working on your Israel Chew Ewan and may provide the answers you seek (if you have not already discovered this yourself). Also, are you related to a Frank Souder who lived in Barnsboro, wife Florence, kids - Lee, Rob, Marion, Jim, Dave & Jon?
