I'm not 100% sure who Carmela's half sister's are ,but I think Ninetta who is the youngest and Rosaria known as Rose are Carmela'shalf sister's . I can't authenticate the information I have on Carmela's line most of which I gathered from family stories regarding Carmela's connection to my family line ,I know that Carmela and my father Francesco(Frank ) were cousins . I have authenticated my line with certificates from Italy , below are my findings on the family connection .
