The entry for Alhang in Ordnance Survey Namebook, Kirkcudbrightshire 1848-151, Vol. 5 gives the following description –
The first syllable in this name appears tolerable plain to be the Gaelic Aill, A precipice, a rock or Steep place but the affix, hang, is rather difficult to trace its derivation. I believe it is much changed by the lowland pronunciation.
The early form Aldhing (Blaeu, 1654) makes the Gaelic ding ‘wedge’  worthy of consideration; however it is pronounced ‘jeeng’. While of course in this neck of the woods the terms ‘hing’ and ‘hang’ are interchangeable but that’s not to suggest it was a hanging hill or Gallows hill!
