I would like to publish a comprehensive list of the british regiments during the period of 1792 to 1815. I've consulted several works like Fortescue or Oman, but after a first glimpse I didn't find a table with the recruiting areas of the regiments - o.k. many names relate to an area, but I assume not exactly with the county. And of course I know the guards and rifles were recruited nationwide.
I found a very interesting image with the areas for the line infantry of ca. 1887.
As I use Swinson Register of the regiments and corps of the british army I know the later amalgamations ... but one question rises: did the recruiting areas of the regiments change between the napoleonic era and the 1880s?
And if someone has a list of the recruiting areas (also for cavarly and artillery) that would be very appreciated.

The Waterloo Podcasts go over the makeup of units in percentage of British, Scots, Irish and foreigners. Seems every unit has some foreigner. I find were army units get their troops a bit fascinating. Russians get pools of new recruits, but every turn I read about Prussia troops are mostly from the units recruitment region.
