Ann Gillott
Evidence that she traveled to Utah in 1850 is based on her marriage occurring in St. Louis in Apr. 1850 and having a child born in July 1851 in Salt Lake. Thus she and her husband could have only traveled to Utah in 1850.
Her name is listed as "Ann Gillott Morgan" on her death certificate and gravestone, and her birth and death dates are confirmed by her death certificate and the inscription on her gravestone.
