Hello,

Sorry for any confusion caused. You're right that this is an unofficial name given to the lane by locals, since it is an unadopted lane with no "official" name. "Frith End" is the village and "Frith End Road" is a different road to this one. I believe "Grooms Farm Lane" is also a nickname but used only by the owners of Grooms Farm, so I think it would be more appropriate for the road to have no name since more property listings refer only to the village, not road name.
It is a private road, but a registered public footpath, so you can run it and I'd recommend doing so because it connects to some other scenic footpaths as well.
