What type of query did you use? Were you using wikitree +? It looks like you were using Country=Oregon. I don't think it works with Country for the US States since United States should be the country. If you use just Oregon for the query, there are lots of records returns and lots of suggestions.
Also if you add Ales as a tag, Ales can answer for certain. Help Page for Wikitree + seems to indicate that the US State would work with a location, but I could not make that work for other states, either.
