I wouldn't consider the first season to be 100% "canon" in relation to the 5 families. I think except for the Jersey and the Lupertazzi family, the rest are supposed to be the same as real life ones since a lot of real mobsters are mentioned throughout the series.. the Colombos are also mentioned by name.
The Lupertazzi family is instead of the Genovese or Lucchese, that much is clear.
I think this is the best explanation
