I’m so glad Giljegiljaw Kungkuan became the first Taiwanese to use his Aboriginal name in the MLB system.
Giljegiljaw is Paiwan. Looking at historical records, Paiwan names should be “Personal Name + House Name.” Although, nowadays there are some confusion among the middle and younger generation about the naming order.
For Giljegiljaw’s case, he is using the traditional order. So his name is Giljegiljaw, and his is of House Kungkuan.
Interestingly, when I looked at the Executive Yuan’s Aboriginal name guide, the spelling of that House name seems to be Kunkuan, without the “g”.
Kungkuan with the “g” means school in Paiwan, possibly loaned from the Taigi or Hakka word kong-kuán (公館).
The name Giljegiljaw seems to be reserved for non-first born male nobles. If Giljegiljaw is to introduce himself in Paiwan, he’d probably say
Ti Giljegiljaw aken a lja Kungkuan.
or
Lja Kungkuan aken a ti Giljegiljaw.
