At its core, genealogy research is detective work. In this fun and informative talk, Sherlock Cohn, the photo genealogy sleuth, will explore how and why it is important to find the clues our ancestors left for us in our family photos. Participants will learn what clues an expert looks for in photos, how to organize your approach to dating and interpreting photos, and how to match photo information with vital records. Additionally, Sherlock will present how she solved “The Case of the Mistaken Date,” demonstrating how accurate dating, photo identification, knowledge of fashion, and records matching can illuminate our ancestors’ lives and help us solve some of our vexing genealogy mysteries. At the conclusion, she will help attendees begin the process of analyzing their own family photos.
