Today I'm going to share with you how the noted private detective Sherlock Holmes guided me to solving a photographic mystery. Being a genealogist is much like being a detective. We have to search through clues and analyze evidence to solve mysteries. Holmes was the first and one of the most famous of fictional detectives. He has many lessons for genealogists, but perhaps the most significant comes from  the very first Sherlock Holmes short story, A Scandal in Bohemia. And that lesson helped me to properly identify a mystery cousin.
