I was born and raised in south Florida on the Banks of Lake Okeechobee.I remember HOT,HOT summer nights,before AC, But believe me it gets cold there. We have always had Quilts. Didn't have bought blankets until I got married. I had relatives at Homestead, Miami FL. That is about 3 more hours south, They also had Quilts. I think it is safe to say unless you are from the tropics in another country, everyone had Quilts.
