Prescot was the Registration District for many towns and villages in Lancashire.
Because it says on the Registration Prescot does not mean to say that they lived there.
Sutton, in St Helens was in that Registration District, as was the whole of St Helens, Whiston, Prescot, Tarbock, Widnes, Cronton, and many other places.
