Using the kinship vocabulary I suggest elsewhere, this might be
represented as:

  JMM daughter JM, JS.   ("JMM has daughters JM and JS")
  JM son J.              ("JM has son J")
  J sister JS.           ("J has sister JS")


  J mother JM; sister JS.  ("J has mother JM and sister JS")
  JM mother JMM.           ("JM has mother JMM")
  JS mother JMM.           ("JS has mother JMM")

Or even:

  JMM daughter JM, JS.
  JM mother JMM; son J.
  JS mother JMM.
  J mother JM; sister JS.

Because the kinship terms refer to their subject's cultural norms, one
cannot conclude whether the above is contradictory or simply different.
