@PoalackJokes88 @WoodshopHandman This was a reasonably reply, which I appreciate.

I do note the following from that article:

"...to the east of the line and in the Mediterranean and particular regions of Northwestern Europe, early marriage and extended family homes were the norm and high fertility was countered by high mortality."

I have a hard time buying the premise that everyone always married in their 20s. But, I will not discuss this topic any further with anyone, because I do not want to lose my account. Thanks.
