Twelve generations ago the feudal lord had what is known as the right of first night - droit du seignoir. Some of those nights could have resulted in pregnancy. Once again, it was the woman who suffered, not the man.
It is very controversial whether that is true or now. Feminists believe it is true, but other scholars don’t believe that happened.
In that city the nobles had a lot of illegitimate children (something like 17% of their children were "out of wedlock"), but the men often saw to it that their sons were set up with an occupation. In my ancestors' case it was architects/stone masons.
The one who had 4 illegitimate children had none by a wife. Maybe the mother was a long-time mistress...perhaps someone he couldn't marry because she was not from a noble family.
Now she's giving it up to Pookie and Ray Ray before looking for a bill-paying simp to "settle" for.
