I just came across a site that had Riley Andrus and James Hudson Andrus, a picture and a biography of Riley Andrus.
The website address is: http://www.migenweb.org/cass/biographies/RileyAndrusOregonBi...

Riley married Ophelia Ann Mattoon

Also see the Descendants of Hazzard Andrus:

I hope this helps the Andrus line of the family!!!
