I am looking for information on my grandmother's family. She and my mother were both born in Fiji and moved to the US in 1945 with my grandfather whom she married during WWII (he was an american soldier stationed in Fiji). My grandmother was born in 1923 and my mother was born in 1944.

I also know that prior to my grandparent's marriage, my grandmother was married to a man with the last name of Stuart or Stewart. This marriage resulted in 2 children (Theresa and Robert). I do know there are still relatives in Fiji and would like to contact them. My great-grandfather's name was Frederick Fremlin and my great-grandmother's name was Teresa Marr. I tried looking up family records (such as birth, marriage, and death certificates) on The Church of Jeasus Christ of Latter Day Saints website but can not find anything. If anyone has any information it would be greatly appreciated
