Dollar
Dollar (population 2,877) is a town with a population of 2,800 individuals in Clackmannanshire, Scotland. It is 12 miles East of Stirling. Dollar was once a home of Mary, Queen of Scots. Feasible analyses are that Dollar is stemmed from Doilleir, an Irish as well as Scots Gaelic acceptation dark and dismal, or from various words in Pictish: 'Dol' (field) + 'Ar' (arable) or Dol (valley) + Ar (high). Another derivation is from Dolar, 'haugh place' (cf Welsh dôl 'meadow'. This word was borrowed from British or Pictish right into Scottish Gaelic as dail 'water-meadow, haugh'). John Everett-Heath, in derives it as 'Area of the Water Meadow' from the Celtic dôl 'water meadow' and ar 'location'. An additional theory, connected to Castle Campbell's different name of Castle Gloom, is that it comes from Scots-French "Doleur", suggesting unhappiness.
