Before we moved here all our houses/flats just had numbers. My parents moved into a small cottage in Yorkshire when they retired and as my mother's maiden name was Lamb, it was named Lamb's Tale - which my children thought was wonderful.
So when we bought this Victorian house, they wanted it to have a name and as we had two tabby cats it was named Tabbycat Cottage.
Around here the town planners thought of a name and then used it over and over again - Park Lane, Park Street, Park Drive, Park Road, Park Way, Park Rise etc. The problem was we kept getting mail/deliveries for the Drive, Road and Street versions instead of our own, so we started using the name and put up a plaque - now everyone, including the postman, calls our house by its name.
