Joseph Sandall
In a brief "History of Thomas Sandall Sr. Family" written by Mrs. Irvin Hennefer of Layton, Utah and found in the "Memories Section" of Thomas' Family Tree, the author, a daughter of Annie Sandall, says that a son named Hyrum died in Boston from measles on 9 July 1860. Lucy, another member of the family, age 2, died 16 July 1860, just four days before the trek began.
