The whole district is (or at least once was) called Arden. Forest of Arden is just one of many contemporary examples of places in Arden being named by reference to Arden.
So I suspect they took the name from Arden, rather than specifically from the forest thereof ..
I agree, perhaps not the best written reply of mine.

However, the aim was to refute the suggestion by Lookin2 that all Arden families went back to the same "ancient family". YT and I are researching the same Arden family in Wiltshire and there are quite a lot in that wider area with so far no obvious links, as happens with many families with the same surname. There may be links but probably pre-parish registers and not confirmable unless they were sufficiently well off to leave a paper trail.
