I don't have an answer but can relate to your problem. I always wanted to write nonfiction but in a literary way. My mother left a keepsake box full of my parents' love letters from their transatlantic courtship and life on an aboriginal reserve in the 1920's. I turned this into a research project. It involved WWI so I went to the war museums here in Ottawa and also the libraries to check out battles, fatalities, ship names, events, etc. They mentioned certain public figures, such as Charles Lindbergh, and I researched him. Cross-referencing of dates of public happenings helped make my parents' story significant. There were facts about all the new inventions of cable, telephone, airplane, etc. to check out on the Internet.
I think what I'm saying is that you have a story people will love to read once you have a personal account to hang the general facts around. I couldn't have invented characters on my own. I looked up books by other authors from the same period, dictionaries of the Cree language. The family memoir, which I also wrote starting from the journals, etc. of both parents, ended up with a bibliography at the back. Have you got a Chapters store where they let you browse in books (eg. encyclopedias) while you drink your Starbucks coffee, or is that an Ottawa thing?
