That's true re: the number of children! though it was interesting see how types of marriage and taking new wives was more common, and then the Church started to curtail those practices but it took a few centuries for it take across most of Europe. There were always a few outliers for children though, some sadder than others. Queen Anne had 17 pregnancies but none of her children lived to adulthood. Some dynasties really struggled for heirs; though perhaps that should be 'male' heirs.

Oh dear! those names would get confusing.
