After the organization of "The Native Daughters of the Pioneers of Washington, Prior to 1870" was formed, encouragement was given for the formation of other Chapters around the State by making telephone calls and putting stories in the newspapers.

In 1918 a decision was made to incorporate and issue Charters to the other Chapters in the State. In 1922 the Association was renamed "The Daughters of the Pioneers of Washington" to include those members whose parents or grandparents had come to the Northwest by that date.

The Constitution had stated that when six Chapters had been formed, the Association would incorporate, and in 1936 this was accomplished (by now seven Chapters).

Active members are female lineal descendants eighteen years of age or older, of pioneers who established their residence in Washington during the year 1870 and/or prior thereto; or in Oregon during the year 1853 and/or prior thereto, or in Idaho during the year 1863 and/or prior thereto; or in Montana west of the Rocky Mountains during the year 1863 and/or prior thereto.

There are now Fourteen Chapters. Activities include the award of two Scholarships annually. Committees on State and Chapter levels are active involvement in the preservation of museums, cemetery records, sites and markers. Individual members are encouraged to write and record family histories.
