PNCu gives an Old English Eald Cote + Norse (v)rá (nook). This last element seems to be productive in the Scandinavian influenced English dialect and is a common place-name element thereabouts, often as "wreay" or "ray". The realisation of vrá is usually /rɛi/ not /ri:/ so the last element might be simply tree i.d. the "Old Cottage by the Tree". Note there is no old form that preserves Anglian ald "old".

There are extensive prehistoric remains which are discussed here.  The interesting thing is that the local pronounciation is given as /æfətri·/ and Mannix & Whellan give Auhertree 1847.  

There is a Welsh place-name coetre meaning "homestead" from coed "wood" + tre "settlement, farm".  GPC gives the earliest extant literary example of Coetre(f) from the 12th Century.

To find coed as cot- in this area would be surprising,unless, as it usually appears as "ceit", unless it was a very late borrowing into English. However, an Allt Coetre is possible - "slope of the farmstead" where the Welsh / ɬ/ might have led to the ultimate pronunciation with /f/.

Another possibility is All Coetre where "all" meaning "rock" is not found in Welsh or Breton or Cornish. It is a perfectly possible Brittonic work and does seem to appear in the Cumbric area, e.g. - All Clud - Dumbarton Rock. The word is found in Gaelic, meaning rock - àl.

I then wondered whether because of the proximity to Ireby, the name contained Gaelic Achadh - "field" which is very common in Ireland and Scotland, but the early forms do not support this. 

If English, the/f/ may come from /aldkɔtri/ → /awkɔtri → aɔχɔtri → afətri/  (I don't believe any Cumbrian says /æfətri/). Or if it was Cumbric Allt Coetre /aɬt kɔitrɛ → aχɔtrɛ → afətri/
