The William Ireland family moved from New York to Galt around 1905. William went to work at the Sego Milk Plant. The two youngest children attended Galt schools. Donald, the youngest son, graduated from Galt High School in 1921. In 1925, he graduated from the College of Physicians and Surgeons Dental School in San Francisco (now the University of the Pacific Arthur A. Dugoni School of Dentistry). After interning for a couple of years, Dr. Donald Ireland opened a practice in Galt. At the age of 40, Ireland enlisted in the Army during World War II. As a member of the 101st Airborne, he was captured during the Battle of the Bulge and spent the remainder of the war as a prisoner of war in Stalag 9C. Upon returning to Galt in 1945, Ireland resumed his practice, passing away in 1975.
