My 4 th generation Maternal Grand Dad was the first one of our English ancestors to have a large family, (10+).
His sons grandsons had 10-12 kids.
From the above, my maternal Grand Dad was one of 9. He had 5 children.
My wife’s English/German/Swiss ancestors had a few children each generation. Then, they came to America and started having 10 +-2. My wife’s Dad, pure English, was one of 9.
Infant mortality dropped during the late 19th century, which was the last time generations of my ancestors overflowed an egg carton. Lots of family tree artifacts exist such as siblings with the same name because the first one died and another carried on this or that name of this or that grandparent or parental sibling.
