Nearby is Tom an Tulaich. The OS namebooks give an alternative form of this as Tom na Tulloch. I suspect this is a rationalisation.
Dieckhoff 1932 gives An Tullaich, but it is not clear which Tulloch he is referring to. It is quite possibly this site however, as his dictionary covers nearby Achluachrach and Roy Bridge, and he probably did gather names in this region.
