Princess Sinaitakala is the daughter of late Kinikinilau Tūtoatasi, 7th Lord Fakafānua and estate holder of Ma'ufanga, and Princess Sinaitakala 'Ofeina-'e-he-Langi Fakafānua.

Through her mother, she is a member of the Tongan royal family and, of her right, in line to the country's throne.

Controversy
The marriage caused controversy in Tonga, since Fakafānua and Crown Prince Tupoutoʻa ʻUlukalala are double second cousins. That is, her parents are each the first cousin of the King:
 * Fakafanua's father is a son of Kalolaine Ahomeʻe, sister to the Queen Mother Halaevalu, (born Halaevalu Mataʻaho ʻAhomeʻe).
 * Her mother, Princess Sinaitakala 'Ofeina, is the daughter of Prince Sione Ngū Manumataongo Uelingatoni Tukuʻaho (known as The Prince Fatafehi Tuʻipelehake), Prime Minister of Tonga (1965–1991) and a niece to King Tāufaʻāhau Tupou IV.

The wedding was opposed by some members of the royal family, reportedly due to the close genetic relationship of the couple. Most notable in opposition to the wedding was Hon. Frederica Filipe who took to the media and social media to voice opposition to the marriage.

Her son, Prince Taufaʻahau Manumataongo, was born on 10 May 2013 and is second in the line of succession to the Tongan throne, after his father.
