I'll be doing my darndest to blow up that last one, and will show it to him Monday (he's coming over for dinner then, assuming he ain't too hung over after Jazz Fest*.) I will let you know if he recognizes anyone ('cause it would be cool as all get out if he knew your GGF.)
*Yes, he will be overindulging in whiskey this weekend, as he does every Jazz Fest, as his little brother (88, and USN for WWII,) is in town for it. Their big brother was also USN for that conflict, but he did not come home.
