Dallas was settled in the 1840s on the north side of Rickreall Creek and was originally named "Cynthian" or "Cynthiana". A 1947 Itemizer-Observer article (quoted in 100 Years in Polk County: A Centennial Background) states: "[T]he town was called Cynthiana after Cynthiana, Ky., so named by Mrs. Thos. Lovelady." The History of Polk County Oregon, 1987, Page 12, states: "To Mrs. Thomas J. Lovelady was given the honor of naming the new settlement and she selected the name after her home town of Cynthiana, Kentucky."
