To answer you question. I put ticks to show how we can join the dots but can only do it through reliable sources if you are not sure is something is a reliable source you can always ask at WP:RSN (reliable sources noticeboard).

Perhaps an example of what you can do with your sources is the easiest way to go. In my sandboxes|sanbox]] I am many others developing an article on  one of the players in that was a man called Francis Windebank (Royalist soldier) as Wikpedia had no article on him, I created one based on the text in the Dictionary of National Biography for his father  see Wikisource:Windebank, Francis (DNB00). To do this I had to extract the article from an OCR version that is kept on Wikisource and put place it where it is now. So having put in the work to extract the article about his father I added said information to his more famous father's article Francis Windebank  With me so far? (BTW. We can copy copyright expired text strait into an article. The dos and don't are explained in the guideline WP:PLAGIARISM).
 
So when I expanded the Francis Windebank article it included the line "Two others (daughters) became nuns of the Calvary at the Marais du Temple, Paris". Marais du Temple was a red-link, so I went on line and discovered that there was little in English on it but there was a French Wikipedia article so I copied and translated the lead from the French article and created Temple du Marais as a stub, unfortunately it still does not have citations, but from the pictures it clearly exists so it has not been put up for deletion. But in creating that article another red link was created Michel Villedo. So I created a stub for that. In that case it was much easier to source because there are reliable English language sources for the man.

So as you can see, one can use an article like minor campaigns of 1815 which has the potential to spark a whole level of creativity with missing biographies. It was your edit to the article that prompted me to look up detail on Charles Auguste Creutzer, and as I found enough I created the stub Charles Auguste Creutzer. But that still leave open the question "how do you know that Siborne was referring to Charles Auguste Creutzer when he wrote General Kreutzer and not some other General Kreutzer? What is your source for saying he was the commandant of the Fortress of Bitsch?". As soon as a source can be found that say that we can modify the text or create an redirect

As to where to put your findings. Do you have a tab next to talk called [Sandbox] if so it should link to  I have about a score, including 3 sandboxes of which the contents of  and a  may interest you, as yet you  have none.
