I've just found information that shows my great aunt, Mrs. Mary Laura (CAMPBELL) HANEY married her 2nd husband, Mr. Gurn E. Town in Coeur d' Alene, Idaho. Both of them had been living in Colville, at the time, and returned to live in Colville after the marriage.
I ordered microfilm of the Statesman-Examiner, a weekly newspaper, through inter-library loan, and found a small paragraph listing names of couples who got married in Coeur d' Alene, Idaho. This small paragraph seemed to be in the newspaper on a weekly basis. Both Colville and Spokane have a courthouse, so why would couples from Colville travel over 2 hours to get married in Idaho? Were the marriage laws in Idaho so different than those in Washington? Were the laws less stringent in Idaho? Were the differences in the waiting period, blood test or something else?
