MultnomahAuto dealer license in Ohio would soon be issued. Multnomah County is one of 36 counties in the U.S. state of Oregon. Although smaller in size, it is the most populous as its county seat, Portland, the largest city in the state. In 2010, the county’s population was 735,334. The county was probably named after the Native American people first record in the journals of the Lewis and Clark expedition, Mulknomans who lived in a village on the eastern side of the current Sauvie Island. (Another theory is that Multnomah is a corruption of nematlnomaq, which means down the river.)
