I'm sorry I don't have any information on James Shepherd but I note that your biological mother Babette Polson might have been born in 1948. Do you know if her father was in the US Air Force and were they stationed in Sioux Lookout Ontario Canada when she was in second grade? If so she was a classmate of mine and I remember her fondly. I would like to communicate with her if she is agreeable.
