Why is the most southern part on the South American continent, Cape Horn, so called?

Question

Part of the continent of South America is in the Northern Hemisphere. This include parts of Ecuador, and, wholly or partly, which six other South American countries?

Answer 1

It was named by a Dutch sailor who was born in Hoorn
Isaac Le Maire, an Amsterdam merchant and Willem Schouten, a ship’s master of Hoorn, contributed in equal shares, with additional financial support from merchants of Hoorn, to a journey to discover an alternative way to the Far East with two ships, the "Eendracht" and the "Hoorn", that left Holland in June 1615. On 29 January 1616 they saw land which they called "Cape Horne [Kaap Hoorn]".
