You should at least start by checking some of the "facts" before freaking out.
After 30 seconds of time wasted:
http://en.wikipedia.org/wiki/John_Wilkes_Booth
http://en.wikipedia.org/wiki/Lee_Harvey_Oswald

One was born in 1838, the other was born in 1839.
I'm not going to check the rest of the claims but you get what I mean.
