A search through Scotland’s Places reveals two other Dingle place-names, namely Dingle Bog (Renfrewshire) and Dingle Burn (Lanarkshire). However, references to a dingle appear in the notes of several other records Scotland’s Places that contain the place-name element den, e.g. Den of Kildrum, Darden Den, Clunie Den and Den of Woodtown, while some contain the additional note – den ‘a hollow, a dingle’ [ Jamieson’s Scots Dictionary] which compares well with the defintion given in the Scots Dictionary den ‘a hollow between hills; a dingle’ 
The hollow in question lies between Dingle Brae and Berry Hill while at the head of the hollow sits Laglass Hill. Michael Ansell identified Laglass Hill as Gaelic An Lag Glas ‘the green/grey hollow’ and considered it ‘may have orginally referred to the boggy area of Star Bog ’, but perhaps the hollow at the foot of Dingle Brae is a more likely alternative .

It is also interesting to note the etymology of dingle  which may also give some insight to the origins of the local place-name The Dungeon – a named glen on the Connel Burn .
From Middle English dingle (“a deep hollow; dell”), from Old English *dyngel, a diminutive of Old English ding, dung (“dungeon; pit”), equivalent to dung + -le.Wiktionary [Aug 2022]
