Perhaps, but possibly not - once she was "married off" she was no longer her parents' responsibility and had to marry again at a young age in order to survive.
My point is that multiple generations of people need to have children at very young ages - often under conditions where they lack agency - for you to know your great-grandparents. It was a great experience for me, but every generation before me had a hard life.
If three generations have kids at average age 22 then you need to be 88 to be at your great grand-child's wedding (if they get married at 22). It's younger than most of us do this these days - I got married at 31 - but there's no need for child brides. Your (very sad) example doesn't seem quite relevant, to my mind.
Having kids at 22 is a significant setback for most people, at least in America. Yes, not as bad as child brides, but it's certainly not the "easy path."
