"We are guessing that her maiden name was probably Emily Tuala-Togaloa."
W-h-y-? are you guessing? I need to know whether you know of a surname or not. What I'm hearing is you have heard of the surname "Tuala-Togaloa" and maybe do not know if it is two surnames hyphenated and they may have been or maybe one is her maiden name. Or because of lack of Samoan name conventions you don't know what to make of a surname that may not be associated with Emily/Emelia at all.
(Remind me to ask you re Fijian name conventions when I get back to the FIJI board - grin.)
Can you share her marriage surname? Her children's names? Her spouse's name?
I have looked under TUALA, TOGALOA (not TAGALOA?), and TUALUA. Checking for an Emily, Emelia, Em, Ema, Eme, or even Emma, nothing under any of the surnames previously listed.
Either the spelling is off, not the correct birth name, or maybe... Amelia?
I'm trying to cut this hunt down, so can you give me her spouse's name? That might help to get to Emily/Emelia faster.
