Reset of history and transporting children

There seams to be a hijacking of our world in the end of the 1700. To manipulate history millions of children all over the world where transported by so called orphan trains. When shipped to a different location it was easy to also teach them a different history.
Even operations like "Pied piper" in the middle of the 1900, children shipped from their parents in England and never returned.
Native americans where send to border schools, forced to change their name and forbidden to speak their own language.
