We found this out about my grandma near the end of her life. Everyone had always thought she'd been born in 1927. Turns out, according to some paperwork we'd gotten from her home country she'd actually been born in 1923. It was all because she wanted to lie to my grandpa and seem younger than she was. At some point she just forgot about it.

We found out about a decade after grandma died that her age may have been off by a few years. She lived in a remote place and a few of the siblings all got their birth certificates in batches on rare (once every few years) visits to a city with a records office. I can't remember what tipped them off about being wrong but I think a few were officially born far to close together.
