Book excerpt: Historical family photos are cherished heirlooms that offer a glimpse into the lives of our ancestors. But the images, and the stories behind them, often fade away as decades pass--the who, when, where, and why behind the photos are lost. In this book, photo identification expert and genealogist Maureen A. Taylor shows you how to study the clues in your old family photos to put names to faces and recapture their lost stories.
