Does anyone know what area is covered by Donnybrook Dispensary District?
Is there a map I can view online?
Try this one - not very detailed though.
Donnybrook dispensary district was basically the township of Pembroke, roughly outside the canal, stretching to Merrion.
The original dispensary was beside the Horse Show House, the edge of the AIB campus, replaced by a house just on the city side of the pub.
That map is the local government electoral areas, but for Pembroke/Donnybrook, close enough.
To be more precise, the map shows District Electoral Divisions (separated by dotted lines) and Dispensary Districts or Registrar's Districts (usually the same). District Electoral Divisions were the building blocks for creating local electoral areas and constituencies.
Scrolling down on the map the information is more precise.
Roughly, the boundaries indicated for Donnybrook show that it covered the old Pembroke Urban District minus Ringsend but plus the section of Rathmines and Rathgar Urban District east of the railway line.
