will, quit deed

Need more information here, is it one of the 3 children who passed or one of the children? If it is one of the children, it will depend on that child's estate plan and what the quit claim says. If there is a right of survivorship, the quit claim now only applies to those still alive. For the will, the specific language is what matters.   Sorry I cannot give you more, but this is all that can be said with the limited information given.
