US pronunciations tend to be rather fluid. There's a part of the city of St Louis, Missouri, called Gravois. The local pronunciation of this changed four times in as many years. There, in a café, I asked for a slice of pecan pie. I pronounce it to rhyme with 'bacon'. The waitress didn't understand at first, but then said "Oh! You mean 'pay-KANN' pie?". That was new to me!
that's where you go when you've got nothing left to lose, Tilly. But actually, I was being treated to a nice meal by a business contact. Not specifically in the pekaan business but I believe he'd eaten a pekaan once.
