“O to A for life and to A’s first child.” (A has one child B.) Which of the following best represents the interest that B holds?

A landowner owned a silver mine as her separate property. She executed a will that provided: “The silver mine shall pass to my husband for life, then to my children, with the issue of any predeceased child taking that child’s share. All the rest, residue, and remainder of my estate I leave to my husband.” At that time the landowner had two children—a son and a daughter. The son had two children—the landowner’s grandson and granddaughter. Many years later, the landowner, the son, and the grandson were involved in a plane crash. The son was killed instantly. The landowner died a few days later. The grandson lingered for two weeks before dying. They left the following survivors: the husband, the granddaughter, the grandson’s widow and sole heir, and the daughter. The husband validly disclaims any interest he may have in the landowner’s estate. Before the estate is distributed, the daughter is killed in a car accident. The daughter left her entire estate to her boyfriend. The jurisdiction retains the common law Rule Against Perpetuities, unmodified by statute. Who has an interest in the silver mine?
