1540.33 – Hattie's Age in 1900
Hattie's age at her death was exactly of the year of her birth. How old was she in 1900?

. That's all there are.
If she was born in 1827, then she died in 1827 + 63 = 1890. That is too soon. If she was born in 1856, then she died in 1856 + 64 = 1920. That works. If she was born in 1885, then she died in 1885 + 65 = 1950. That also works.
So Hattie was either 44 or 15 in 1900.
