As part of the commemorations for the start of World War I, Ancestry has released a new resource. Called U.S., Army Transport Service, Passenger Lists, 1910-1939, it’s a database containing images of the passenger lists for ships that carried U.S. troops during the time period 1910-1939. Each list includes details on the ship’s departure or arrival (if they were coming to the United States), the names of the passenger, their service unit, and their next of kin and where those next of kin were living.
Why is this database helpful? First, it confirms someone’s service in the military. You even have unit information, so you can learn more about their service by searching regimental history. Second, it can prove relationships. Some next of kin listings include how the two are related: cousins, mother, etc. I found a few Connecticut families who might benefit from checking out this source.
