Sheindel Margolioth

There have been questions as to how Sheindel margolioth could have a daughter called Sheindel.
Sheindel (aka Schondel) bat Moshe Mordecahi Margolioth married Menachem Mendel ben Joel Feivish Shtengen. He took her name (margolioth) and became Menachem Mendel Margolioth. Together they had 7 children. Sheindel died 22/3/1652 and Menachem Mendel remarried. He had several children with his second wife and they called their daughter Sheindel. So Sheindel was bat Menachem Mendel Margoloith but her mother was not Sheindel.
