Keep in mind that in some ethnic backgrounds reusing” names of deceased children was a very common practice. One of my ancestral couples from Ostfriesland, Germany, had four daughters named Reenste born within a ten year time span. The first three died shortly after birth. The fourth one grew to adulthood. Other families re-used names of deceased children, but usually there were not as many children as there was in this case.
Some individuals will name children after previous spouses who died during the marriage. That may seem a little bit unusual today, but there was a time when it was not unheard of.
And my genealogy software program thought I was nuts to have a family with four children with the same name. But it can happen.
