The last time I was at the Gilliam Co. center where the Historical Society keeps their files they were not on microfilm. (That was last year) They have the actual old newspapers but they do not let people peruse through them due to their delicate condition. What they do have is a hard card system which is indexed by last name. They have cut out articles and obituaries and pasted these on the cards! It is quite impressive! They will let you photocopy the cards (for a small fee). They have cards back to the 1800's.
I don't know if the newspaper office has it on microfilm,I was always referred to U of O library when I would ask, and the newspaper office never seemed to be open when I was there...bad timing!
I have the book 'A pictorial history of Gilliam County' which I purchaed at the museum, and they have several other books available too.Again, they are more than generous with helping you find information. Check with the museum about their hours...they were open 1 p.m.-5 p.m. My book is not indexed but if I come across any pictures of your Farrar, Allen & Tipley line I will send them.
I have a history of the fore mentioned Campbells from Scotland, if your line connects to theirs, I will be happy to scan it and send it to you. They are not a direct line for me, so I have not done the research.
