Actually, although there are a couple of false ones mixed in, a good number of them are in fact true. Snopes tries their hardest to disprove this, but most of what they end up saying is "It's just coincidence." You can read it here: http://www.snopes.com/history/american/lincoln-kennedy.asp
As you will see, there are a few ones that are false, and there are a few listed in the post here on FS that aren't mentioned on Snopes, and may or may not be true. But there's no denying that there are a lot of coincidences involved here.
Assuming the country is still around then.
