I email a cousin that has more on the Barnes family than I do. I can't exactly recall where in Oregon they lived. I think some were in/near a town named Elgin (or similar to that). I'm not for sure, but she might be able to answer your question. Try her at : CDeripaska@aol.com
Barnes in Cuba, MO? My Mullen fmaily is from Cuba and I've been working on that family tree for over 14 years, now.
