I know the following facts about my paternal grandfather: 1) his name: Alphonse, 2) he fought in World War I, 3) he got the flu during the Spanish flu epidemic of 1918 and never fully recovered, 4) he died when my father was two years-old, and 5) he was peculiar. Okay, that last one isn’t so much a fact as an opinion, but still, you get my point about the scant information.
