Grant County, Washington Genealogy Guide

Grant County, Washington (Map It) was created on February 24, 1909 from Douglas County. The county was named in honor of Ulysses S. Grant (1822–1885), 18th U.S. President. In the late nineteenth century, the county was traversed by railroads: the Great Northern; the Northern Pacific; and the Chicago, Milwaukee and St. Paul. The railroads brought settlers into the county, attracted by its rich soil and agricultural potential. The Columbia Basin Irrigation Project of the 1930s also made a significant impact on the county while the completion of the Grand Coulee Dam (the largest all concrete structure on earth) opened lands for farming and furnished electric power for industry. Today the county is a major bean and pea producer and food-processing center. Learn More About State of Washington History.
