Many articles on identifying old photographs don’t go beyond suggesting that you
should ask older relatives if they recognize anyone in a picture. This is a great start,
but it’s a mistake to believe that this is all you can do. Forensic methods of
photograph analysis are important tools for recovering at least some of the
information missing about a picture. When interpreted correctly, old photographs
can yield an abundance of genealogical information, either directly revealing facts
about family members, or serving as a point of departure for further investigation.
