I will for now (RfC) stop the creation of these older cats, and will move on to much more recent subjects (from about 1850 on, most from the 20th century). This will mostly mean adding categories to articles, but in some cases this will also mean creating cats, mostly filling gaps between other year cats. If you notice that even these are a problem, just drop a note and I'll stop this as well, but I think (hope) these will be mostly uncontroversial. They will also in general be limited to one new cat, not complete trees of 10 or 15 cats.
