Died Sept. 6. 1835.
Aged 22 years 3 months
and 21 days.
Using only the death date and the exact age, what birth date do you get for Nancy?
Correct
Not quite
Subtract in order: 22 years gives Sept. 6, 1813; 3 months gives June 6, 1813; 21 days means borrowing the 31 days of May, which gives May 16, 1813. Higher up, the same stone says she was born May 15, 1813: a one day difference is common, because people counted the days differently. Treat a computed birth date as a close estimate and look for a birth or baptism record to confirm it.
