Hi:
Don't know if this is relevant or not. My Great grandfather has listed on his Marriage Certificate a Robert and Mary Murray living in Glencoe/Glen Levit New Brunswick as his parents. In reality his Mother was Cathernie Murray a daughter of Robert and Mary. I don't know if this is the same Mary or Magaret Murray or not. I am having trouble finding anything out about Robert Murray but I think he may have come from PEI..
Again, this is a long shot.
