Ok so I have to do a Source analysis , explaining the usefulness of each source to an historian studying the impact of the war on women's lives and experiences in Britain, making reference to the perspective and reliability of each. If for one particular source, it has no date, no author and no origin, but through research I made an educated guess at who the author is, I found out more information about him that would lead to changing the intended audience and therefore the reliability, how do I write my answer this question? :/ Thank you in advance!
