Dollar
Dollar (population 2,877) is a small town with a population of 2,800 individuals in Clackmannanshire, Scotland. It is 12 miles East of Stirling. Dollar was when a home of Mary, Queen of Scots. Possible interpretations are that Dollar is stemmed from Doilleir, an Irish and also Scots Gaelic acceptation dark as well as dismal, or from different words in Pictish: 'Dol' (area) + 'Ar' (arable) or Dol (valley) + Ar (high). Another derivation is from Dolar, 'haugh area' (cf Welsh dôl 'meadow'. This word was obtained 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' as well as ar 'place'. A further theory, linked to Castle Campbell's different name of Castle Gloom, is that it stems from Scots-French "Doleur", implying despair.
