She wants to get
    married, and her mother got pregnant with her without being married
Question

                When my parents did niqqa, my mother was
      already pregnant with me. My father has now passed away.As I will be getting married soon, I was told that my younger brother
      cannot be my walee and that during my niqqa, my name cannot be mentioned as
      "binte" with my late father's name. Is this true?This will cause suspicion, and I want to avoid embarrasment to my
      family and cover the fault of my parents since they have taubah. Is there a solution to
      this? As a child outside of wedlock, I know that I am sinless, but I'm wondering why do I
      have to bear the burden of my parents old sin with this complicating matter for niqqa.
      Insha Allah, Allah will not place a burden on His servant greater than he can bear.
Praise be to Allah.It was reported in a saheeh hadeeth that the child belongs 
  to the bed and the stone is for the adulterer, so it is not permissible for 
  the child to be given the name of the adulterer or of the mothers husband. 
  Rather, she should be called after her mother, so that her name will be So and 
  so the daughter of So and so [her mother]. Otherwise, her guardian should choose 
  for her a common name that cannot be attributed to any specific person. For 
  the girl who is asking this question, there is no sin on her at all because 
  of her parents sin, and if she is patient in putting up with any annoyance 
  as a result of it, she will be rewarded for that, in sha Allaah. And Allaah 
  knows best. See also Questions # 6195.
