"and Mary the mother of James and Joses, and the mother of Zebedee's children." Matthew 27:56
You should read the Bible sometimes. Scripture is really not clear if Mary or Salome (or both) was the wife of Zebedee. The construction of this passage could go either way.
If Mary was the wife of Zebedee, then James and Joses were not Zebedee's children...There's only one way that can be read...Mary is one person and the mother of Zebedee's children is another...
