Dear WRG, Perhaps our astute groupe can offer direction on the following puzzle that has lingered for many years on my desk as unsolved. In 1926, my grandfather mysteriously disappeared, Chicago being the last suspected area. At the time of my obsessive search, I spoke to Ginger LaVire, director of "Unsolved Mysteries" who wanted to run a segment because of its compelling story content. I finally backed away for reasons of privacy, and I felt that there was more to add to this story by further research. This was indeed the case. I was able to uncover a known picture of my grandfather taken about 1908 when he would have been 5 years old. Shortly thereafter, a large oval framed bubble glassed picture was found with my grandfathers name written on the back. I had a costume analysis done in Boston and found it was probably taken between 1910 and 1920. This picture is of a young man, perhaps between 15 and 20 years old. The confusion lies in the fact that my grandfather had the sa! me name as his father, and quite possibly the name on the back of the picture was the photographers notation as to whose family it belonged. And, the family to whom this large picture belonged, had always assumed that it was of my grandfathers half brother. I do now have several pictures of my grandfathers half brother for comparison. The above prefacing leads to this: I would like to positively identify the large picture as my grandfather or his half brother for obvious reasons. A few years back, only the FBI Crime Lab had skilled personnel to age or study the physiogamy of pictured individuals. My question is whether this analytical process has advanced and now exists in private labs or universities. I can envision a highly technical computer program, but don't know whether a 5 year old boy can be aged 10 to 15 yeqars. Analysis of the half brothers pictures may also give some clues. Does the Group know where to go with this one? Suggestions invited. Larry Tracy Jr. Kennebunkport, Maine
