Description: After Sonora became an adult she realized the selflessness her father had shown in raising his children as a single parent. It was her father that made all the parental sacrifices and was, in the eyes of his daughter, a courageous, selfless, and loving man. Sonora's father was born in June, so she chose to hold the first Father's Day celebration in Spokane, Washington on the 19th of June, 1910.
