Where I live the roads names are theme based [poets/birds etc]. I used to live in Capsey road, surrounding ones were excalibur, lancelot, guinevere, merlin etc. Who or what was Capsey? was it really Merlin's cat?
I just had a look and it does appear just to be a surname. There are well over 100 entries, mainly from the USA southern states, including the names of a couple of rivers. No mention of merlin, cats or any other history.
