Could the mountain in this article be where "Mountain Hill" is/was located?
AUGHNAMULLEN, a parish, in the barony of CREMORNE, county of MONAGHAN, and province of ULSTER, 3 miles (S. by W.) from Ballibay, on the road to Dublin; containing 18,032 inhabitants.
It comprises, according to the Ordnance survey, 30,710 statute acres (including 1643 1/4 under water), of which 26,468 are applotted under the tithe act and valued at £19,323 per annum: there are large tracts of mountain and bog.
The mountain of Bunnanimma is an isolated mass about six miles in circumference, and its summit, which, according to the above survey, rises 886 feet above the level of the sea, is the highest point of land in the county: the waters flow from this mountain on the south-east to the sea at Dundalk, and on the west-north-west to Ballyshannon.
On the south-east part of it is Lough Eagish, or Crieve Lough, partly supplied by springs and partly by rain water, which descends from the heights by which it is flanked on the east and west.
A stream issuing from it presents by its rapid fall and constant supply, together with the abundance of fuel furnished by the bogs in the neighbourhood, such favourable sites for bleaching-mills that not less than fourteen mills are situated on its short course northward to Ballibay water, the tail race of one serving as the head of the next below it: the lake is under the care of an engineer, or waterman, to regulate the flow of water, so that a deficiency is seldom experienced even in the driest seasons.
There are many other lakes in the parish, the principal of which are Lough Avean, Lough Chantinee, and Lough Ballytrain, besides several of smaller size. - - - - The rest of the article is at http://www.libraryireland.com/LewisA/Aughnamullen.phphttp://www.libraryireland.com/LewisA/Aughnamullen.phpQuite interesting, including the urn found...
