I like the namefinder, when looking for Carshalton Road, in Carshalton (one of several), it picked up several other Carshalton Roads elsewhere.

• Carshalton Road, Camberley, Surrey - In an area whose roads are named after towns in this area of South London


• Carshalton Road, Swindon - Area using London places as road names


• Kingstanding, Sutton Coldfield - Again, using London placenames


• Carshalton Street, Croydon Park, Sydney, Australia - The link to Croydon is fairly interesting, ex-pats?
