I live in a French speaking part of Canada but am originally from the Netherlands. My name starts with a W (Willem). In Dutch W sounds a lot like a V, just a bit less fricative. When someone asks me how my name is pronounced, and hears me say it, they go "ooohh, so it's pronounced with a V". Sometimes I demonstrate the difference by pronouncing my name with a V and then with a W, but most of the time people don't hear much of a difference, and to them it just sounds like I am pronouncing it with a slightly different V both times. More often though, people have seen my name in its written form before we meet, and since this is a French speaking part of the world, I automatically become Ouilemme.
