English = England. If it wasn't for the French, Spanish and Dutch, Americans might be able to even speak English today.
Americans = Bastardisation and woeful misuse of an original language, but everywhere/thing IN America is copied from Britain or taken from the First Nation tribes.
The English language in itself was heavily bastardised by French.
The purest English accent today that is closest to Old English is probably the Scots (not Scottish) accent spoken in Scotland because the Normans never set foot there.

Northern English was also less Frenchified than Southern English accents. They also had a lot more Norse influence.
