Rhoda Lee (US14002b) died 15 May 1915 aged 74 years, 4 months and 15 days. A software date calculation tool gives the resulting birthdate as 31 Dec 1840. The death certificate says she was born 31 Jan 1841. It seems the death certificate is in error (it is only as good as the person supplying the information) as the 1850 census implies she was born about 1838.
