  == British politician categories ==  If I understand correctly, you've started subdividing Category:Members of the Parliament of Great Britain into chronological categories. This classification should still be orthogonal to the division of that category by geography (English, Scottish, and Welsh members). (I ask because I re-added the parent category to Hugh Boscawen, 1st Viscount Falmouth, saw you'd created the chronological subcats, and changed it to a geographical subcat.)
