In the 1870 Utah census she is listed as Mary Perkins age 61, living in the household of R. Perkins of Bountiful but born in England. On the 1862 manifest of the ship William Tapscott she appears as Mary A. East, a 52-year-old widow from England. Church ordinance records prove that Mary East, born 8 May 1809 in England, arrived in Utah in 1862; Perpetual Emigrating fund records show her arriving that year.
