you mean 1891.

someone on this board (sorry I forgot who, but you deserve to be credited) did the math:

in 1901, young Vito at the age of nine years old came to Ellis Island on the boat. this was obviously not in wintertime, so the winter (December) of 1901 would still come. That would be his 10th birthday.

probably the only mistake is in fact the Senate hearing saying "1950"... if you move that up about five years, Senza Mama's story would be wright.

it can't be 1902 when the films opens, nor can Anthony's communion be in any other year: THE ONSCREEN TEXTS SAY 1901 AND 1958...

there's a good timeline on J Geoff's site about the birth dates of all characters, including Fredo's (1919) which would make him 26 at the wedding. What's wrong with that?

What much more confusing is, that in the novel, Vito's already about eleven or twelve when he emigrates and this rises a lot of questions:

was born earlier (1888)? or did he go to the US later (1903)? and the wedding with Carmella would move up a couple of years, as would the birth of Sonny and Tom (1916 according to J Geoff, while in the novel they are around 35 yrs old at Connie's wedding>1910!)...

I've thought about all of these minor 'errors' a lot, but just don't see to get a good view.

then I decided to extract the movie from the novel, them being completely different works of art.

but it's still sad that, even with Puzo nearby, the movie couldn't follow all of the novel's details (remember Vincent Mancini?)...
