These historical notes with no modern-day relevance to OSM will get 'resolved' which means they will disappear after about a week. I suggest you find a more suitable, permanent place for your knowledge, maybe Wikipedia pages or maybe you should start a blog. You could use markers on there to OSM maps so people understand the locations and you can add descriptions there that will never be used in OSM. Setting up a blog can be free on, say, Wordpress or Blogger
