Maria Hester, how your name can be passed on when you don't have children

Maria Hester, I ran into the name when I was researching my ancestry. Maria Hester van Stam is the youngest sister of my ancestress IJda van Stam and of Simon van Stam, about who I also wrote a blog. A name that is not very regular. In my not catholic family there are not many women called Maria, but Hester... I never ran into that name before during my searching in archives. Nowadays you sometimes hear this name, but in the early days? Well... it drew my attention. And it even drew more attention when I ran into it again a few minutes later, but now with a different surname. What happened?

Maria Hester van Goor, her surname is also mentioned as Goor without 'van', was born in 1759 and baptised on January 7th of that year, in De Meern, near Utrecht in the Netherlands. She was the daughter of Anthonij van Goor and Maria Duijn. On April 17th of 1791 she marries, in the Meern, Cornelis van Stam, the uncle of IJda and Simon. Maria Hester is than 32 years old. As far as I can find now, they didn't have any children. But I do have four other, younger, Maria Hesters in my ancestry. How come?

I didn't find Maria Hester's parents nor if she had brothers or sisters. I only have her husband's family. When children were born, the first were named after the grandparents, following children after their parents or aunts and uncles, or a favorite other family member.

Maria Hester's brother- and sister-in-law, Frans Stam and Ariaantje Verkaik, have a son in 1796 who is named Wijnand. Maria Hester is witness when he is baptised. In 1799 this couple have their fifth child. It is a girl and they name her Maria Hester. So this girl is named after the sister-in-law of her parents. She must have been a very popular and loved family member. Maria Hester and Cornelis had been married for eight years at this point and didn't have children of their own. Maria Hester was 40 years old. Apparently nieces and nephews stayed at Maria Hester's and her husband's home regularly. The niece Maria Hester had an older sister named Maria. She dies in 1814 at the age of 16 years old and in her death certificate is mentioned that she died in the house of her uncle Cornelis van Stam. In Maria Hester's house! I think she might have been ill and Maria Hester nursed her during her illness.
