But assuming Anthony was born in '51 he would have been 4 when he saw Vito die, and the child in that death scene looks about 4, which puts Vito's death as 1955. Because there are tomatoes growing, we can assume it is summertime.
I don't think the killing of the heads of the families was much longer after that,
The little boy who portrayed Anthony was actually three years old. Vito's tombstone lists that he died July 29, so we can safely presume the Great Massacre happened only a few weeks later, somewhere in August or September at the very latest.
