I too am looking for information on this. My Grandmother Recently passed away and I had always had intentions of asking her about her great grand parents.
We are members of the Muscogee Creek Nation in Okmulgee and I recently looked up my Great Grandmothers information on the Dawes Roll to find that her last name was very unusual in comparison to others.
Her name was Jemima Aupeka and Her sister was Setty. Jemima was born in 1893. On the Dawes roll it shows she was enrolled by her aunt and Uncle William & Nancy Aupeka.
The Roll lists my great grandmother'sparent's Una & Louisa as "Arpueka" and Una's father as Makakpoyah.
There seems to be several spellings of the name "Aripeka" as well as my family's name "Apueka". I am looking for the possible origins of our family name and wondered it they were perhaps loosely related.
