ontai family origins
I am looking for information about the Ontai family before the 1850's. The furthest back that I have information on is:
Ng Ah Cheu (Ontai)[male], born in Canton (Kuang-tung), China on December 23, 184?
And his first wife:
Shee Ching Zane [female], born in 1850 in Canton (Kuang-tung), China and died on December 14, 1892.
I would love any information on the generations before this, meaning both Ng Ah Cheu and Shee Ching Zane's parents and grandparents. Im looking mostly for Hawaiian last names to see where the Hawaiian bloodline entered the Ontai family (at least two of Ng Ah Cheu and Shee Ching Zane's children [Henry and Carl] attended Kamehameha Schools, but both parents have China listed as their birthplace??)
Any information would be so helpful! Thank you!
