Welcome to Washington Co. Oregon

As you can see this county is up for adoption which means it needs someone
 to fill it with all kinds of free information. That is our goal here at the Genealogy Trails and we need lots of help to make that happen. Please check out the volunteer page to read about taking on a county yourself.

Until we can find a permanent host I would be happy to accept any contributions to this county. I will also be adding as much new information as I can. You can click on the logo above to explore the other states that make up this project! I hope that in these pages you can find something that helps you in your search. If you have any comments, questions or contributions please email me.

Thank you and good luck.
