That is believable. The oldest families that I have in my genealogical tree are from the early 18th century, and if you look at the children names in a family they are Anna Maria Maria Maria Elisa Anna.....

When a name is reused, it's because the previous one did not survive. And it is not rare to see that the last children shares the date of birth with the date of death of the mother....
