aloha,
the most interesting thing is all the names you are mentioning like tu'ifao, anae, nanai, and even the vaafusuaga now are all related to us also. I believe our great granddad Pasi had quite a few brothers and sisters, like you said, we just might meet in Savaii, a ea? like they say "e leiloa lava ala o vae"... you take care and God bless you and your family.
