Elizabeth Ann Capener

Her name is shown as "Elizabeth A. Carpenter Hardy" on her death certificate, and it confirms her death date.  Her death certificate shows her birth date as 22 May 1837, as does her obituary, but FamilySearch gives her date of birth as 23 May 1837.  The inscription on her gravestone confirms the years of her birth and death, but does not include the days or months.

Note that her obituary gives the year of her arrival in Utah as 1850, but she actually came with her parents in 1852.
