Hopefully you had a fruitful summer. Now you get to spend the winter putting all your research together and making a list so you can do it all again next year. Definitely it is a never ending hobby and/or obsession. There could be worse addictions.
My grandfather in WWI embarked from Hoboken to Europe. Do you know where yours left from? Try and find the unit, division, or regimental history of your loved one. It can be quite informative and eye opening.
Hopefully you are as lucky as I to have letters from a grandfather who was in WWI.
Until next time,
