Lots of Asian children are given anglo names (or change their names when they move here) and children from parents with different backgrounds often choose a name from one of the cultures over the other so I don't really see an issue with it to be honest. I'm sure in Sweden there are kids that don't look Swedish who are called Sven.

My girls both have French names but we are not French - DD1 actually looks Spanish. We were even looking for Thai middle names for DD2 as that's where she was conceived but in the end DD1 chose the middle name.

Plus so many people just make up names these days anyway so it's sometimes difficult to know if a name is from another culture or is one that has just been invented by the parents.
