I grew up knowing my ancestors in what felt like a two-dimensional way. They existed in pictures, occasionally in conversation, but there seemed to be no life animating them.
Perhaps one of the most exciting experiences is for a two-dimensional picture in an album, or on a wall slowly to start to turn into a three-dimensional human being. Discoveries, conversations, connections start to give bones and flesh, voice and breath to a previously lifeless face and body. This has started to happen with mine.
