How about 'Dderwen'? It's Welsh for 'oak tree'. (No, I haven't got a clue as to how you should pronounce it!).
You can have some fun, coming up with some more Welsh ideas here:

But remember that you should always check online translations by reversing them. For example, that site states that 'view over the valley' translates as 'golyga ar 'r bant'. Unfortunately, asking it to translate 'golyga ar 'r bant' back into English gives the meaning as 'I edit signs'! ;-)
