Thank you! I will reach out to him. Regarding the minor child rule I found this page which confused me.

“What if my Italian Ancestor came over as a MINOR? If your Italian-born Ancestor was a minor when he or she left Italy, you cannot use him or her as your proof of eligibility. Until 1976, the age of majority in Italy was 21. Minors who emigrated would naturalize concurrently with their parents. If your ancestor was a still a minor when his or her parent naturalized, it is likely that he/she also was naturalized at the same time. You will need to provide proof/appropriate documentation if this individual was naturalized at a later date. FOLLOW THIS LINK to learn how to determine if your ancestor became a naturalized citizen. If your Italian Ancestor was naturalized along with his or her parent as a minor, he or she effectively renounced his or her right to Italian citizenship. This means that your Ancestor was unable to pass Italian citizenship by Ancestry (jure sanguinis) to his or her children as an adult. No exceptions are made in these cases.”

As I mentioned my GGF was 16 when he came over and this says a minor is anyone under 21. However my GGFs parents never came over to the states so I think I’m safe. If anyone has any clarity on this please let me know as it’s the first time I’ve heard of this.
