How to Pronounce "LeBlanc"

So, I saw a thread for how to pronounce , and people were arguing over It is not JUST French; it's Cajun French - I was born and raised in Louisiana, where "LeBlanc's" is a huge grocery store chain. The way we're raised to say it is either "Luh Blahn kuh"/ "luhBLONK" (thanks to Der Lindwurm for correcting me) or "Luh blon" will fix later when i figure out how to type the pronunciation better LOL
