text: Good catch, but the Redford node is south of the Aderg polygon. Either the old node has been misplaced somewhat and we should add Redford as an alt_name to the Aderg polygon, or Redford corresponds to a different area than the Aderg townland.
  
  My money is on the first guess, but it'd be nice to confirm via survey. I very vaguely remember "redford" being signposted when I walked that road years ago. I'll have an opportunity to resurvey in the coming months.
