My great-great-great-grandparents went to Oregon Territory in 1852. My great-great-great-grandmother died on the Oregon Trail in Clackamas County (without having served on any juries). Her husband settled near Silverton in Marion County. I went to Salem about ten years ago to do some genealogical research but just stayed on the freeway when I was driving through the Portland area.
You’d probably enjoy a book called The Empire Builders, by Robert Ormond Case. It’s a series of short historical stories about Oregon, from Capt. Gray crossing the Columbia bar to statehood. I read it when I was a kid, then recently bought a copy to reread.
