If I remember correctly, all of his children died without having kids of their own, one in war. I think he only has indirect descendants.
I watched a movie on youtube called Murder on the Atlantic i think and it was about Lusitania being torpedoed by a German u-boat "U-20" As the U-boat was not having much luck they were thirsty for an target of big size, they had 1 torpedo, low fuel and supplies. So they shot a torpedo out setting it's speed at 30knts, as the liner was carrying ammunition at the time it was classified as a enemy ship. When the torpedo hit, the ship's speed was 18knts and funny thing they also yelled out hard to Starboard. She went down in 18 minutes, but here the captain did survive. When he was taken to court, he was going to be prosecuted because Naval High Command officer put a lot of dirt on him, but overall it was his fault for not doing enough to save the ship and taking so long to send the warnings. Overall in the finally result the theory was that the ship was hit by more than 1 torpedo, Captain did his best of his abilities and everyone went home. This was a mistake done by the U-boat's captain and this started the war with Germany, Americans and British were really angry now. The war With Germany took 5 years, 14 million civilians were incapacitated, I think 250 thousand American casualties and 15 or 14 million American soldiers returned home. Finally as the Russian Army was 200 meters from reaching Hitler as he married his love of his life, he pulled the trigger on himself to he head.
