Good starting points for your research are the two official websites for the Presidio of San Francisco, the NPS and the Presidio Trust. On the official NPS website there is this page on “History and Culture” which gives you thematic links to people, places, stories and collections (with old family pictures, portraits, historical pictures of places at the Presidio). Here the Presidio Trust website. By the way on the same website read “Lovers’ Lane: One of San Francisco’s Oldest Travel Coridors“.
