Higgens Point? Or Higgins Point?

From Idaho Dad: Here’s a question for the HBO readers …Is it Higgins Point (about 5 miles east of Coeur d’Alene), or Higgens Point?The State of Idaho and Wikipedia has it with an “e” while the BLM and FYI North Idaho have it with an “i.” Doing a Google search on it, I was surprised at how many government and news organizations differ on the spelling.
