She couldn’t save her daughter, who had slave children on an adjacent plantation, and wouldn’t leave because she’d never see those children again. And it’s untrue that Tubman only saved her relatives. Visit the museum in Cambridge, MD and the Visitor Center outside Cambridge on land where Harriet was once a slave. Her birth name was Araminta Ross. She was married to a Tubman before he left her. I never learned why she changed her first name.
I read about her some time ago. The only evidence is a book written by someone who knew her with zero evidence to support it.
Tubman could not read or write.
I don’t doubt that you will find thousands of stories about it but no real proof.
The whole thing about her came out when they wanted to put her face on a twenty dollar bill.
