Dedicated to helping researchers appreciate and explore the social history aspect of their own genealogy, Gena Philipbert-Ortega, in her article, Using Postcards to Illustrate your Family History, once again provides us with multiple links to great resources. With an emphasis on postcard collecting and enhancing your family's story through postcards, Gena directs us toward those great photo postcards of family members so popular at one time, and historical postcards of the times, places, and events that may have figured into your family's history.
I might also add, that you want to watch carefully for postcards received from family members, whenever searching through old family photos. These postcards are not only interesting, but can serve to document certain people in a specific time and place. I found postcards among my grandmother's photos from my uncle serving in France during WW II. I also found postcards from my aunt during their trek along the Alaska Highway back in the early 1950s, not long after the highway was first completed. Postcards are just one more of these often overlooked, non-traditional sources that may add one more piece to the puzzle.
