Tolkein's Orcs influenced by pigs...?

[Mr_Ed7]

While Tolkein as stated the etymoloy of his orcs, he had to have known of the Orkney Islands in North Scotland.

The Orkney Islands (according to Wiki) were named for a Pictish word meaning pig or boar.

I can't help but think that the Picts themselves may have been some influence on his fictional monsters.

The Picts of course played a key role as antagonists in the Robert E. Howard Conan series.
