I just read your message. My mother told me that uncle Sagato had passed away. Uncle 'Sagato' is who I am named after.
I believe we may be related. Salome your grandmother is my grandfathers sister. My grandfather is Filipo Fidow.
I have a family tree that suggests that your father Tovio, was 4 of 8 children from Salome & Lavea.
There is a Fidow Family Reunion to be held in Samoa July 2013 @ Tofamamao Cultural Centre Leauva'a Village.
This Family Reunion is for the Uuga Jacob & Tumema Family linage. Uuga & Tumema was your grandmothers parents.
Let me know if you need anymore details.
