Lewis County, Washington Genealogy Guide

Lewis County, Washington (Map It) was created on December 21, 1845 when the provisional government of Oregon divided the District of Vancouver into two large counties: all land north of the Columbia and west of the Cowlitz Rivers was designated Lewis County. The county was named in honor of Meriwether Lewis (1774–1809), the co-captain of the Lewis and Clark Expedition. The county's early settlers expended much effort and time in cutting and building roads through the vast forests that covered the land. In 1873 the Northern Pacific Railroad passed through the county linking it to the Puget Sound settlements; the county seat, Chehalis, was built to accommodate the new railroad.
