If someone is interested.. I was in contact with a woman who published a listing of Post Offices in 1831. Of course Oregon is not listed back then, mainly more states to the East. I think it is very interesting to find out what post offices were around back then. If anyone would like a copy of this book, she is selling it for $15.00 plus postage of $ 3.20 = $ 18.20. If you are interested please email her: PR102@AOL.COM and she will give you her address and can answer any questions you may have. She also told me she is publishing one for the 1850's also. Thanks.
