As far as I know we are not related to the Fonoimoana family, my sister however is, because her mother is a Fonoimoana and Afalava. I need to know more info on what your family names are in order to see if we are related on your father's side, do you have your family tree? If so, I would like to see it. From there I can tell you all that you need if indeed we are related, it's a strong possibility, if you have su'a paia cousins, so please let me know your family info in detail and I hope to talk to you soon. If you are having trouble in translation, we have family that can help you out with that.
