Not Newmill, Sparky. Try my clue about its whereabouts: 'Not Sancreed unless you're a churchgoer'. People who attend a church roughly describe themselves as belonging to a certain ....? You were closer before.
Mot Newmill, Sparky, as that's in the Madron/Gulval parish, nor Tredavoe, missp. That's in the Paul Parish, isn't it? You're not recognising my clue in the last comment, I think.
Skimmel Bridge is about halfway between Tremethick Cross and Sancreed, tpp - it takes the Sancreed road over the stream which feeds into the north-eastern arm of Drift reservoir.
Could the hamlet be Grumbla?
