The information on the stillborn daughter comes from the Rhode Island Vital Records department. The index is online at Ancestry.com. It shows Bill's birth, Lillian's, and then an unnamed daughter on September 13, 1915. This was a year after Lillian's birth on June 27, 1914. It also shows a death entry for that child on the same day, so she was either stillborn (most likely) or died shortly after birth. Jack's birth also occurred in Rhode Island and is recorded in the records (May 29, 1919).
