Interesting. Found my grandfather's WWI draft registration. Three males in my dad's family fought in WWII - only thing I found was the grave site for 1 of them. Had three family members in during Vietnam - none listed. A long lost relative that fought in the Mexican American war - was actually quite a war hero in Tennesse and Mississippi in the 1830s and 1840s wasn't on the list either ( this particular relative is well documented in the Mississippi archives ).

Seems just a little incomplete at the moment.
