Some of our ancestors (or events they are associated with, such as battles) have entries on Wikipedia. Most are related to English and European royalty. As I find them, or other Internet sources of biographical notes, I'll add them here, and on their individual pages as links, to avoid duplicating the work of others (and copyright infringement).
