I thougt now days you only had to be 100% Italian on your fathers side because you are what your father is, I read that somewhere but I can't quote the source.
What you're quoting is Gravano, who talked about it in his book and ABC interview. In New York in the late 1980's and 1990's that was the case. You only had to be Italian on your father's side. In the early part of the 2000's that was supposedly changed back so now the general rule is you have to be 100% Italian. I say "general rule" because there will always be well connected guys who might get made even though they aren't 100%.
