From where is the last name "Ko"?

Question:This is what www.ancestry.com has to say about the name,
Ko
Chinese : Min (Taiwanese) form of Ke.
Chinese : Cantonese variant of Gao.
Chinese : variant of Ge 1.
Chinese : variant of Ge 2.
Korean: there is only one Chinese character for the surname Ko. There are ten different Ko clans, but they are all descended from the Ko clan of Cheju Island. There is no historical information regarding the founder of this clan, but there is a legend which tells of three men who appeared from a cave on the north side of Cheju Island’s Halla Mountain. These three men were the founders of the Yang clan, the Pu clan, and the Ko clan, the latter being named Ko Ul-la. Some days after the three men emerged from the cave, a box was washed up on the shore of the island. In the box were three women, horses, cows, and agricultural seed. From these beginnings, the three established Cheju Island’s T’amnaguk kingdom and ruled peacefully. Ko is a common surname found throughout the Korean peninsula. Approximately ten percent of Cheju Island’s present-day population consists of members of the Ko family.
Hungarian (Ko): from ko ‘stone’, a word from the ancient Finno-Ugric word stock of Hungarian (cognate with Finnish kivi, Estonian keve), hence a topographic name for someone who lived on stony ground or by a notable outcrop of rock, or alternatively a metonymic occupational name for a mason or stonecutter.
hope this helps.
