Nearly every house in our village has a name, and we are about to name ours.
When we bought the house there was a lovely little cat living here which we adopted, sadly she's gone now. So we're going to use her name. It will just be a little plaque by the front door, not part of the official address, but I may add it to my correspondence etc.
When walking around the village I try to guess how some of the house names originated; a lot are flower names, some are foreign words or combinations of christian names, or 'The Old School House/Bakery/Forge' etc. Our postman often mentions houses by name, so they do notice them, not just the road numbers. It seems to be a very English custom to name houses and more often found in rural areas than in towns/cities.
