Hoddam (or Hoddom), par., S. Dumfriesshire, 7514 ac., pop. 1548; contains Ecclefechan.
A Vision of Britain through Time includes a large library of local statistics for administrative units. For the best overall sense of how the area containing Hoddom has changed, please see our redistricted information for the modern district of Dumfries and Galloway. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Hoddom and units named after it.
