Mine is my registered prefix with the British Goat Society for the goats. So they are all Ballingall something. When I was wee and wanted to register it, I wanted someplace local but that began with my initial (B for Beth), so the bridge at the bottom of our road was Ballingall Bridge and I used that.
I sometimes use vale which is part of our house name. And orginially I used to use babe after babe the pig, and because I look anything like a babe!
