Could original surname have been LEVI?
Do you know of another spelling for TAIMALESUA? Taimalesua does not show up as a forename. Do you know other aiga/Family surnames/forenames?
Only other possibility is your grandparents are still living.
Your spelling is probably correct but the Polynesian spelling(s) for LDS database for TAIMALESUA is not. And to this day I run into incorrect spellings submitted by LDS members and non-members alike for Polynesian data - grin.
