An alternative name for the hill, ‘Suidi Celi’ or ‘Suide Ui Ceallaig’, possibly dating to the medieval period is provided by Patrick Healy who reported that Montpelier Hill;

‘may be identified with a hill named “Suidi Celi” or Suide Ui Ceallaig which is mentioned in the Crede Mihi of the twelfth century. This was situated in the district known as Ui Ceallaig Cualann, which included the northern portion of Glenasmole, and Mount Pelier is certainly the most prominent elevation in this area.’ (9).

Another name, ‘Cornaun’ appears to have been in use for the hill in the nineteenth century, as described by Alice Furlong in 1895:

‘Right away in front of me like a barrier across the vanishing point of the road was the cultivated slope of Cornaun (Anglice, “the little bowl- shaped hill”), familiarly and indifferently known as Mount Pelia, Mont Pelier, and Mount Pelion’ (10).

We may take this name as being used, at least locally, in the late nineteenth century as the writer goes on to state:

‘Seen from here, it is a shapeless block of a mountain, ungainly in configuration, but beloved of me for that I have known it all my life…’ (11).

No other direct references can be found to support the name Cornaun for Montpelier Hill, though another ‘Cornaun’ is mentioned as being located in the Wicklow
Mountains near Rathdangan, in association with the Byrne family (12).  Alice Furlong suggests the name may mean ‘the little bowl-shaped hill’ and as such, it may have been applied to more than one mountain or hill in Ireland.  However, given Alice’s professed love and familiarity for her Cornaun, we have no reason to doubt that this name once applied to Montpelier Hill, although perhaps only informally or locally, in the late nineteenth century.
