The siblings were hapa-haole or part Caucasian, but considered of aliʻi (royal) class through their mother, and John Young's honorary title of "Olohana".

She allowed her daughter to be adopted by her sister Grace Kamaikui and her husband Dr. Rooke according to the Hawaiian tradition known as hānai.

Her father John Young died at her sister's home in Honolulu on December 16, only three weeks before Emma's birth.

He had been living there for some time under Dr. Rooke's care, and it appears the Young family, including Fanny and Naʻea, gathered in Honolulu, perhaps in anticipation of his death.

It is unlikely the Rookes would have allowed Fanny in her last stages of pregnancy to risk the health of the baby by sailing the rough channels to Kawaihae or Lahaina.

All the other women eligible to become monarch were there: his half-sister Princess Ruth Keʻelikōlani, Bernice Pauahi Bishop, Queen Emma, and Lydia Kamakaeha Dominis.

Her funeral on October 3 was marked by the absence of any members of the reigning Kalākaua dynasty, except for Archibald Scott Cleghorn[12] Fanny was buried in the Wylie Tomb in the Royal Mausoleum of Hawaii known as Mauna ʻAla.
