Do you believe Angelo Yale was born in 1898 or 1903, since his marriage certificate and age at his father's death indicate its more likely that he was born in 1898
If he was born in 1903 then its likely that he might have been a Camorrista by age at least age 16 if not sooner
He was Frankie's kid brother. I believe 1903 is correct for him.
And back then, there was such a thing as young camorrista and mafiosi too for that matter.
