Well of course it is... Tolkien was a fetishist for anything in UK history and the Vikings/Saxons are a fairly big chunk of that. Hence alot of the names he creates, uses for people, places and creatures are yanked effortlessly from all those obscure parts of Viking/Germanic myth that didn't get made into opera by Wagner. As Ashildr is basically the OE (old English) form of the modern Hilda and OE is what you get when Germanic languages and half forgotten latin collide..
Although what would happen if someone called 'me' Hilda I hate to imagine, something along the lines of black eyed and veiny I imagine.
Thankfully we were spared the experience of Moffats take on Pervy Hobbit Fanciers although, if you squint you could kind of see Clara with hairy feet and a pipe..
Just for the love of <insert deity here> don't mention carrots...
Or blowing the Horn of Gondor.
