Thanks Moss,
I thought the same thing.
"Tarka", a fictional account of a west country otter which celebrated both the animal and the landscape of north Devon. "Tarka" in Williamson's etymology meant "little water wanderer"

"Tor"
"high, rocky hill," O.E. torr "tower, rock." Obviously cognate with Gael. torr "lofty hill, mound," O.Welsh twrr "heap, pile;" and probably ult. from L. turris "high structure" see tower). But sources disagree on whether the Celts borrowed it from the Anglo-Saxons or the other way round.
