I never really thought of this before, but not only am I descended from immigrants, but I am descended from ILLEGAL immigrants.
My great-grandmother was from Lithuania. I've always loved her immigration story. She was four years old when her family decided to flee Lithuania on the eve of the Bolshevic revolution. They escaped the country in a wagon with a false bottom and entered the U.S. with papers from a dead Polish soldier. They lived in the U.S. for ever and ever with the name Nowodzelski. I can't remember what their Lithuanian name was.
It was easy to fool the government before they had computers.
