This is a huge stretch, but I just came across this post today..many years later. Please, if anyone knows how I can contact Mark Quinn or his family, I would be grateful. I have his families paperwork--I purchased this large amount of paperwork from an antique shop and swore I would find John's family.
More specifically, I have his grandfathers information. His military records, death certificate and his grandmothers information as well. Along with many letters from Italy to Felomina (in Seattle WA), from her relatives in Italy. Her maiden name was Felomina Traficante. I have more names, but I cannot find Mark Quinn. Believed to be living in Michigan. Please, any info--I will start a new thread in hopes of finding someone.
