For nearly a century, Camp Mystic has been the Hill Country respite for Dallas’ daughters.

Three girls from Dallas, 8-year-olds Hadley Hanna and Eloise Peck and 9-year-old Lila Bonner, were among the missing Camp Mystic campers.

Sally Sample Graves was a grandmother who was killed in the flooding, the BBC reported. Sarah Sample wrote that a massive wave destroyed her grandmother’s home. Sarah Sample’s father and his dog were also in the home at the time but both survived.
