There were plenty of 13 year old child brides, but very few child husbands... Strange how the child brides never married another child. Until the 1940s it wasn't uncommon to see preteens and teens working hard labor, does that mean it was ever OK?

I also doubt it was ever the "norm" in the modern civilized world. A quote from wikipedia [1]:

"In the last decades of the [16th] century the age at marriage had climbed to averages of 25 for women and 27 for men in England..."
