Where does the name 'Castlegar' come from?

For well over 90 years the most frequently asked question in Castlegar has been "Where does the name 'Castlegar' come from?."
The theories have been many and varied but it is now certain that the name originated in County Galway, Ireland where, in the Parish of Castlegar, there is a tiny village of the same name.
Adjacent to the village is Castlegar Castle, now in ruin, built by De Burges family. The name 'Castlegar' comes from the Celtic Irish 'An Caslean Gearr', which means 'The Short Castle,' since, as legend has it, no guest ever stayed there for more than one night.
Here Is the True Story!
Edward Mahon came to BC from Castlegar, Ireland, in 1890, using family money to invest in mining sites in the area. He didn't do a great deal of actual mining, but bought and sold properties. In 1891 he purchased 320 acres on the west side of the Columbia and had it platted for a townsite. He gave mineral names to the streets, ie, Platinum, Silver, Galena, Iron etc. He named the area after his home in Ireland, Castlegar. The home in Ireland was built in 1815, replacing an older home. The property had been in the family for many years. Castlegar is a big, comfortable place and in Edward's time, the property encompassed a large area of land which, under the British system was inherited by the eldest son. Castlegar was sold late in the last century.
Edward Mahon shortly moved on to his primary interest, development of Vancouver. His elder brother on an earlier visit to Canada believed that Vancouver had a bright future as a seaport on the Pacific. Edward Mahon became a real estate developer and is recognized as a pioneer in North Vancouver.
