Hi Greg:
I see that you know he was in
Coos County around the 1870's. You might already have this, but just in case:

Rogers, formerly of
Roseburg, has assumed the position of host at the Central Hotel,
Marshfield.
Most interesting of all is an article from the Oregonian, November 21, 1904. It has more answers for you regarding his family. I can't seem to get it to attach, so if it doesn't, send me a message with your email address and I will email it to you.
