Eligibility: Any female eighteen years of age or older who is a lineal descendant of pioneers who established residence in Washington during the year 1870 and or prior thereto; or in the state of Oregon during the year 1853 and or prior thereto; or in Montana west of the crest of the Rocky Mountains during the year 1863 and or prior thereto. As to what the organization does, I have no clue. I had only received one newsletter from them -- Lewis County Branch. Lewis County is behind, I know that. They promised us information when we joined and so far we never received it and that was 2 years ago. You need to check the branch you will be associated with and they will be able to explain what their organization is about and can do for you. Michelle
