While digital photos snapped with smartphones are fairly common means for sharing photos today, digital photography hasn’t been around all that long. Prior to the 1990s, printed photographs were the primary means for sharing images. Many times, someone in your family will have saved photographs and even labeled them, which can be another big help in identifying the family who’s who.
Photography has its origins in the 19th century. You'd be surprised how many really old photographs have survived into the 21st century. In some cases, some of the old photographic processes look fresher than photos that were developed in the latter part of the 20th century. And, hopefully, someone in your family took the time to identify who the people are.
