I live in a village where most of the houses have names.
Our old farmhouse has a one-word name. (let's call it "Dunroamin*)
Attached to my house are a row of cottages, which are called "1, 2 and 3 Dunroamin Cottages"
Except the owners of have put a sign up proudly calling it "Dunroamin" and then miles away from it a teeny tiny number 1 sign.
Couriers, visitors, etc all go there and it is ANNOYING.
To change the name in all the Royal Mail, deeds etc is about a grand 
Can we start calling it Dunroamin House and it be legal?
