The Washington State Postmaster Index, Cowlitz County is a set of index cards that lists all of the post offices that operated in Cowlitz County from 1851 until about 1965. The index cards are posted at FamilySearch.org.
From the index, we learn when each post office was established (and discontinued, where applicable), the names of each postmaster, and the dates they served. Many of the cards include additional information, such as the names of spouses and other relatives, date of death, etc.
Abbreviations/terms:
(est.) = date the post office was established
(re-est.) = date a post office was re-established under the same name, and/or in the same location as an earlier post office
(disc.) = data post office was discontinued by the U.S. Postal Service
(rescinded) = indicates an order that was rescinded by the U.S. Postal Service
View the index alphabetized by name (below) or by post office.
