Father-graduated high school. Went to a community college for two years. I supposed he got an Associate's degree or whatever the equivalent was at the time. After a stint in the army and getting married, he completed his Bachelor's degree by taking night classes while working days.
Mother-was forced to drop out of high school the day after she turned 16. According to her father, "girls don't need an education." This would have been about 1948. She had to get a job and help support her siblings, which included her older brother's college tuition. After she married my father, she went back to get her diploma or GED. A combination of night classes and the on-line school of the era, correspondence courses.
My grandfather relented on the girls don't need an education BS a bit because he let his younger daughter complete high school. But no college, unlike all four boys in the family.
