Hello Elizabeth, my name is Trina and I am married to Allen Hisatake who happens to be your cousin from American Samoa. Allen's parents have resided in Aua, Am. Samoa for years, but I know a lot of your family history. Your grandfather Harry had 4 brothers--Pioi, Tutuila, Charlie, & Jack. His 2 sisters were Eleanor and Laila (the youngest). Grandpa Harry was the 2nd to the oldest and was the father of Anthony Faipa Hisatake who happens to be my father-in law and is the only one of his siblings who has passed away. Harry's wife Fale or grandma Fale is burried right next to the Hisatake residence. So yes your Hisatake family is alive and well in Aua.
If you have any questions, let me know.
