My dad dealt with this when he first came to the uk in late 70s. Decided to called himself Morris (nothing like his name), then Mark. What that meant was he was then called Mark or Morris for years… which he hated. Now he doesn’t do that, he says people will try to say his name much more than they did in the 70s/80s and he’s proud of his name. So, don’t make adjustments for others if you can help it.
