As time goes by, more of the recent past is documented online. Take, for example, something my grandfather did during the Great War:
The President of the United States of America takes pleasure in presenting the Navy Cross to Quartermaster Second Class Philip J. Strahan, United States Navy, for extraordinary heroism and devotion to duty while serving on a steamer used in experimental mine sweeping on the North Sea barrage. In a gale and heavy sea, the main topmast broke in two, the upper part dropping down and whipping around. Quartermaster Second Class Strahan jumped into the rigging, and at great danger to himself, cut the part adrift.
Either the site misspelled his name or the spelling changed slightly in the last century because his descendents on that side of the family spell it Strachan, not Strahan. I know it is him because I have the medal and the letter explaining why he got it upstairs (the site I link to above leaves off the part where he kept his captain from going overboard or that due to a too-close encounter with a mine they were detonating, most of the caulking in the ship had been blown out and they were taking on water).
