"December 1, 1880, the townsite of Dufur was platted by E.B. and A.J. Dufur, Jr. The patent to the land which comprised the original townsite was issued by the United States to C.W. Brohack, September 16, 1872, and at once came into possession of Joseph Beezley. A few days later it was purchased by E.B. and A.J. Dufur who retained possession until the platting in 1880. Connected with the material advancement of Dufur will be remembered the names of Hon. A.J. Dufur, his three soils, Dr. L. Vanderpool, E.D. Bohna, William Heisler, A.J. Brigham, the pioneer merchant, C.W. Williams, D.E. Thomas, J.A. Guleford, A.J. Brigham, W.R. Menefee, George Nedrow, Johnston Brothers, (T.H. and G.W., who purchased the business interests of C.A. Williams.)"
William Heisler worked as a tobacconist in Pittsburgh after he left home at age 17. Then he enlisted as a soldier in the Mexican War; his unit, Company A of Colonel Powell's battalion under Captain Sublett, was assigned to guard the Oregon Trail. After the war he worked at gold mining in California. Following his marriage in 1851, he travelled by covered wagon on the Oregon Trail with family and neighbors of his new wife to the Willamette Valley of Oregon, settling on a donation land claim (similar to homesteading in the midwest.) He pursued a variety of jobs, including farmer, cattleman, miller and storekeeper. Before he died in 1905, he was known in the town of Dufur as "Grandpa Heisler." Martha McConnell Heisler was similarly known as "Grandma Heisler." (source: Susan Molye)
