I think Douglas MacArthur and his Father both were awarded the medal of honor. The WW2 award may have been a little suspect but I have read of his (and a lieutenant named Patton’s)conduct in WWI and they both were extremely brave.
I think TR and his Son also were both awarded the medal.
Yes, Theodore Roosevelt and his son both received the MOH. Teddy received one for his heroic actions during the Spanish-American war, his son received the MOH for his actions on D- day.
