Who cares about Sonny's twin daughters?!?!?! They played no prominent role in the running of the Family, nor would they ever.

A good point to bring up though, was that Sonny & Sandra's youngest son (who was a baby when Vito is shot and therefore would be slightly older than Vincent) is just as nonexistent in GFIII as are Connie's children. With Anthony as uninterested in the Family Business as he is portrayed to be, what a classic rivalry it would've been to have all these male cousins involved in the story. Tom Hagen's son the priest is in my opinion present ONLY to make up for the absense of Robert Duvall and as an excuse for Michael to mention Tom's death and therefore explain him out of the film.

Such a shame when you think of what a good movie this could've been.
