Dilley’s history is mostly unwritten

Horace and Marilda Parsons settled in the area located south of Forest Grove in 1849. In 1850, Parsons built a grist mill along the Tualatin River near what later became Dilley on the land claim of William Owen Gibson. Gibson settled his claim in 1847, and built the log cabin used for Tabitha Moffatt Brown’s orphan school that later became Pacific University. Dilley School District 10 was established in 1860, with a school built on the north end of the town that same year. A flour mill was added nearby in 1863, and Joseph Gaston’s West Side Railroad reached the area in 1872. James C. Chamberlain, was the first postmaster of the post office established on December 31, 1873.
