The Tri-City Genealogical Society was founded in 1961 as an organization whose purpose is to educate members and the public on the purposes and methods of genealogical research, and to research, record, and report materials of genealogical value for the people of, and those researching in and around, the Lower Columbia Basin region of eastern Washington state.
