Thousand Island Dressing

I was a freshman in college when I was introduced to Thousand Island Dressing https://en.wikipedia.org/wiki/Thousand_Island_dressing. We made our own, out of mayonnaise, ketchup, and whatnot.  I never much thought about why it was called Thousand Island Dressing. I am aware of the Thousand Island Region between Canada and the United States on the St. Lawrence Seaway https://en.wikipedia.org/wiki/Thousand_Islands, but duh! never associated the two.  Well, while watching Mysteries at the Museum http://www.travelchannel.com/shows/mysteries-at-the-museum, they did a presentation on the "controversy" of the origin of the recipe.  They concluded it was Sophia LaLonde  who originated the recipe.  That is neat!
