Minerva Plymale Armstrong

Minerva Plymale Armstrong and her husband Robert traveled with her parents and siblings from Illinois to Oregon in 1852 along the Oregon Trail. They settled on a farm 4 miles north of Jacksonville at the base of the western hills overlooking the beautiful valley to the east of Old Stage Road. One of their 11 children, Cornelius Jasper Armstrong, born February 24, 1853, is a contender for the title of “first child born in Jacksonville.” In 1890 the Armstrongs moved to town, purchasing the small “saltbox” style home at 375 E. California Street, historically known as the G.W. Cool house after the individual who constructed it around 1858. Cool had received his Doctor of Dental Surgery degree from the Baltimore College of Dentistry. He came to the West Coast in 1850, practicing first in British Columbia and then in Washington before settling in Oregon. The house was both residence and dental office. However, his practice appears to have been lackluster since a mechanic’s lien for construction costs was attached against the property. By 1861 Cool had moved on to Portland. The next decade saw him in San Francisco where he did experience success and was one of the first members of the California State Dental Association.
