I only just learned that Alice Huang happens to share a family name (at least, its romanized spelling) with Jensen.
> at least, its romanized spelling
Almost certainly the same last name (黃/黄, huang2). It's also sometimes romanized as Wong (though some Wongs are 王, wang2).
You mean like John Smith and Jane Smith? About as common.
Along with another 35 million people. Huang is one of the most common surnames in Chinese (and Vietnamese and Korean).
