''Kalolaina Mapa ''and ''Tevita Mapa ''were commissioned by the LDS Church to gather oral genealogies throughout Tonga during the 1970s. There are over 800 Tongan oral genealogical interviews, which they gathered on reel-to-reel tapes. The tapes were transcribed, and the transcripts were microfilmed. In 2006, the tapes were transferred to compact disc (CD) in order to preserve them.
