Hello John.
I remember seeing a WWI war medal (I think it's called something like "Honor Roll", but I honestly can't remember).
When I was in Loughrea in May 2009 for a family reunion, I was visiting the shop of my cousin. He showed me the medal, it was about 3 inches in diameter. He gave me a book to read, but I can't remember if the story of the Furey brothers was a Chapter in the book, or just a section (it was only a few pages in length). Again, I can't remember the details, but the book was talking about 4 or 5 brothers killed/wounded. (I remember thinking about the movie "Looking for Private Ryan", and making the similar connection when I was reading the story, so 4 or 5 brothers was the number that sticks in my mind.)
Anyway, the medal was sold to another man who also dealt in memoribilia. A few days later, we were honored with a tour of this other man's home, and I saw that medal on one of his tables. I flat out asked him "How did you get the Furey medal?" He was VERY surprised -- almost shocked -- that I knew what it was (probably because I'm from America, and was visiting all my cousins for a 2 week period, and it wasn't likely that I would know local history), then I explained that I had held it a few days earlier and had learned its history from my cousin.
Would you like me to try to find out if this medal might still be in the other man's possession, and if it might be available for purchase? Remember, though, that was 3 and 1/2 years ago, and it might not be in the other shop anymore.
I just looked up Irish medals from WWI on the internet and found a website that has images. I think the medal was a "Death Plaque", so it probably was not your grandfather's, but most likely it was one of his brother-in-law's medal.
I also just found this at the Loughrea website which might be of some interest (it's about your grandmother, Catherine Furey's brothers-- the sons of William Furey and Mary Ward) I'll bet that one of the people on the Commemorative Committee would be of more help, if you're interested : http://www.loughreaonline.com/2012-11-10fureyfamilyandthegreatwar.php
Thank you!
