I was stationed in Alabama from 1973 to 1976, and knew several guys in their late teens and early 20’s who married local girls who were 13, 14 or 15, because the girls parents gave their permission for them to marry.
I grew up in this era of the 1960s 1970s in alabama. While rare for 13 and 14 year olds, I probably saw four 15 year old girls marry.
At some point in French history, it was accepted for 12 year old girls to marry. Maybe nationally, some folks are freaking out, but most Alabama folks over 50 remember how it was.
