His profile says he was born in Brawinston, England. As far as I am aware, or can find, there is no such place.
I suspect that this can got mistranslated from Braunston or Braunston-in-Rutland which given the other location of Rutland is the most likely place. Not difficult speechwise to move from Braunston to Brawinston
No records found for Name: Johannes Edward Warde, Event: Any, Place: Braunston, Event Range: 1550-1650, Spouse Name: Maria Hatton, Country:England
Edit to add: Having looked at some other profiles I think personally that Johannes moving to London and marrying Mary / Maria may be OK but unless they were on the move to Liverpool and a port I think it unlikely that, if William is their son, he was born in Warrington. People just did not move around that much.
I may be completely wrong on this next point but I thought that most of the early emigrants left from port like Southampton, Plymouth etc.
