Hi Murray, Thanks very much. You've put alot of work into that. I'll assume than the administrative districts map would be relevant to the districts used when Protestant marriage civil registration began in 1845 and for all civil registration events (including marriages for all) in 1864. Lewis Topographical Dictionary of 1837 describes each civil parish but doesn't list the townlands in each. The Ordnance Survey Memoirs for County Down unfortunately aren't as detailed as those for the southern counties because they apparently were under time constraints to complete them since County Down was one of the last counties finished.
