Hi Marie - my mother is Noatia McCarthy. Her father was Malaki McCarthy and his parents were Sale Malaki McCarthy and Tautala Ilaoa. Sale Malaki McCarthy's parents were Malaki Charles McCarthy and Mary Groat [spelling of Mary's last name varies]. Mary is german. Email me and I can send you some genealogy information I have. You can email me at firstname.lastname@example.org
There is a cousin here in Hawaii, Farina McCarthy-Stonex, who's father or grandfather was Robert Prout. Do you know her? I'm sure we are related. I look forward to your response.
