Without any doubt the biggest contradiction in the entire timeline is the 55 massacre being said to take place in 51
I agree 100% despite olivant's and Turnbull's protestations. Part II starts in 1958, at Anthony's first communion. He was born in 1951, and was already 3 years old reading the funny papers when Vito died. The massacre could not have been 1951.
That aside, the whole timeline is a weak, poorly written part of the movie/novel.
