Hillsboro Genealogy Records
Hillsboro is the county seat of Washington County and a strong base for genealogy research in northwest Oregon. The city was founded in 1842 and has deep ties to the earliest settlers in the Tualatin Valley. Searching for Hillsboro genealogy records means working with county offices, a local heritage center, and state archives. These sources hold vital records, land files, photos, and much more.
Hillsboro History and Records
Hillsboro was founded in 1842, making it one of the oldest communities in Oregon. The city was incorporated in 1876. It was first called Columbia, then Hillsborough, and finally Hillsboro. The name honors David Hill, a prominent early settler who played a role in the founding of the town. For genealogy, knowing these name changes matters. Older records may use Columbia or Hillsborough instead of Hillsboro.
The Tualatin Valley drew settlers in the 1840s because of its fertile soil. Families came west on the Oregon Trail and claimed land in what would become Washington County. Hillsboro grew as the county seat, with a courthouse, shops, schools, and churches. These early settlers left records in land claims, tax rolls, church registers, and court files. Each type of record can help you build a Hillsboro family tree.
By the late 1800s, Hillsboro was a thriving farm town. The railroad arrived and linked the city to Portland and beyond. This brought new families and new types of records. Railroad employment files, business licenses, and city directories all date from this era. In the late 1900s, the tech industry transformed Hillsboro. The population grew fast. But the old records remain, and they are the foundation of Hillsboro genealogy research.
