Hi -

I suspect that this is a corruption of Meary Vooar, and accordingly it is on the coast of Santon, between Douglas and Castletown. The new all-Island Sewerage Reclamation site is under construction next door at Meary veg.

The alternative would be Eary Moar of which there could be a number, I think there is one above Glen Helen, adjoining the back of Greeba Mountain, in the parish of German.

Hope this helps.

Nigel
