Margaret Krasiowna was a woman from Poland who claimed to have been born in 1654 or 1655 and died in 1763, aged 108. Doing some research I found that if she had actually been born in the 1650s, her youngest children would have been born to her when she was in her 90s. Case DEBUNKED!

She was more likely born in 1704/1705 and was 58 when she died, NOT 108. This would make total sense as she would have been 49 when she had her last child. Still unusual to have a child at 49, but not impossible.
