Sir Ralph de Stourton is connected to this profile as her husband but despite a very full overview on his profile there seems to be nothing pointing to this marriage.
If any of the managers of this profile can provide evidence then I will reconnect it but in the meantime I am going to detach this profile in the belief that she did not marry Sir Ralph de Stourton.
Generally there seems to be agreement that her parents were unknown however I did a google search and found this Wiki tree but it doesn't agree with what we've got:
