From genealogist Solomon Lehuanui Kalaniomaiheilu Peleioholani (in Ancestry of John Liwai Ena):
Look at Kaulahea (k). King of Maui. Kaulahea (k) niaupio married Kalaniomaiheuila (w), his own sister; and born was Kalanikahimakaialii (w), wife of Kualii (k) of Oahu. Kalanikahimakaialii (w) married Kualii (k) of Oahu and had Kapiioho (k) Peleioholani I (k) Kukuiaimakalani (w). Look at this the mother of these Oahu chiefs is a Mauian and part Kauai and Oahu; also Kualii is King of Oahu.

Look at Peleioholani I (k); he is the grandparent of Kalaniomaiheuila Peleioholani.
