Isabel Moscrip - Parents of Isobel Moscrip

Just wondering if anyone has found any conclusive evidence of Isabel's mother being Elizabeth Turnbull. I know her marriage mentions that her father is called William. The only records I have been able to find for potential parents are for William and Elizabeth, but just because there apparently aren't any other records, it doesn't make these the right ones. Has anyone found a will or death record or siblings' death records that can provide more insight?
