Why is it always the ladies who don't seem to be able to get their age right?
There is no easy answer to this, especially since your Hannah was born pre-1837. I have three gt-grandmothers of varying degrees of greatness who just do not seem to age consistently:
Amelia
1851: aged 59 (born 1791)
1861: aged 75 (born 1786)
1871: aged 87 (born 1784)
1876: aged 91 (on burial record and death certificate, born 1785)
To make matters worse, she was really Millicent. I think she was actually born in 1788.
Elizabeth:
1861: aged 9 (born 1852)
1869: aged 19 (marriage certificate, born 1850)
1871: aged 20 (born 1851)
1881: aged 34 (born 1847)
1891: aged 40 (born 1851)
1899: aged 47 (death certificate, born 1852)
Her birthday according to the Family Bible was in March 1850 - the only two registrations I can find in the correct area (she couldn't be consistent about that either) don't make sense of a March birthday. She wasn't with her parents for the 1851 census, so I'm going for 1852.
Margaret:
1875: of full age (marriage certificate, family story said she was 16!)
1881: aged 34 (born 1847)
1891: aged 33 (born 1858)
1901: aged 46 (born 1855)
She was born in Ireland so this one could be difficult to find out for certain. She had her last child in 1895.
I don't think I'd mind being able to reduce my age by one year in ten, as Margaret did, but I think I'll pass on the eleven children.
I hope you find an answer to your puzzle.
