She was one of two daughters of Otto Peter Ankerson, overseer of a large sugar plantation near Bacolod. Her mother died in 1925 when she was young, so Ardis, along with her older sister Ruth, attended grammar school and began high school studies as boarding students at the Brent School in Baguio City. In the early 1930s, the girls were sent to San Antonio, Texas, to complete high school. She attended Texas Woman's College for her freshman and sophomore years, 1934–35, and was named the Freshman Class Beauty in 1934, chosen by modern Dancer Ted Shawn.
