"You may get a screen that says you have 500 other places of that same name with England - do you want to remove England for the other 499 also? Reply yes."
This may be a potentially dangerous thing to do.
Suppose that 300 of those place names only have the word "England" in the Place Name field. If you tell it yes to remove the place name couldn't/wouldn't you end up with 300 Place Name Fields that are completely blank
I don't know the answer to this but a word of caution is in order
