Once again, you don't know what you are talking about! There are only two primary sources for Ambrosius, and they are Gildas (the main source) and Pseudo-Nennius (who makes use of Gildas, plus adds in some snippets of chronicle material and folklore), both of which are cited in the previous version of the article, along with secondary sources such as Bede and Geoffrey and reliable, modern scholarly sources (Chadwick, Woolf, Gidlow, and Fleuriot are all respectable scholars). You need to leave this article alone if you unclear about the sources.
