Are you familiar with the surnames:
EPENESA? GALUMALEMANA? MOEA'I? SAVEA? TAGALOA? Just to name a few.
You really need to speak to someone (in your family) that would know the "oral history" of the "aiga/extended family". The surnames above are only a few surnames associated with the name Elikapo SALE.
Before you research anyone in your family, ask the eldest or someone familiar with SALE family lines (keep it short and have serveral visits) and - please - it's always best to work backwards. You'll find yourself moving forwards quicker. That is why we love older lineages because there's more mystery, more adventure, more family!
