Augustine Washington, George Washington's father, died from a sudden illness at home at age 49 when George was 11. Unfortunately, history does not record what specific illness he died of, but it seems to have some kind of gastric distress. (In his will he describes himself as "sick and weak, but of sound sense")
No, George Washington did not die of strep throat. He passed away on December 14, 1799, after suffering from a severe throat infection, which was likely acute epiglottitis or a similar respiratory illness, rather than strep throat specifically. His symptoms included difficulty breathing and swallowing, and he succumbed to complications from the illness after just a few days.
