Yesterday's post mentioned men who might have had wives with the same first name. Keep in mind that in some ethnic backgrounds "reusing" names of deceased children was a very common practice. One of my Ostfriesen couples 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.
And my genealogy software program thought I was nuts to have a family with four children with the same name. But it can happen.
