He was born in Manchester, so, yeah, he's British. Americans like to say our country is the "great melting pot", but Ireland, Scotland, England and Wales are far और mixed culturally and ethnically than the United States is.
The दिया name of Severus is of Roman origin; several politicians had the name, such as:
Marcus Didius Severus Julianus Augustus
Lucius Septimius Severus (my personal favorite)
Marcus Aurelius Severus Antonius Pius Augustus (also known as Caracalla)
Marcus Opellius Severus Macrinus Augustus Pius Felix
Flavius Valerius Severus Augustus
Libius Severus Augustus
Out of all of them, only Lucius Septimus Severus died of natural causes; all the rest were murdered या executed.
Britian was part of the Roman Empire; could this signify our heroic and long-suffering Potions Master is of Roman descent? His father's name, Tobias, is a Greek version of the Hebrew name Toviyah, which means, ironically, Yahweh is good. Many surnames began as the name of the place where the family lived; Snape figures in the name of several locations all over England, and his father's family could have come from any of them.
His mother, Eileen Prince, was described as looking just like him, with black hair and dark eyes. Eileen is a common name in the Isles, it is the anglicised version of Irish Eibhlín, which is in turn a form of the older Irish Gaelic Aibhilín. The surname Prince could have come from anywhere, really, France, Germany, Spain, the Isles themselves, even the Netherlands (I myself have the surname Prins in my Dutch family).
आप really can't judge a person's nationality just द्वारा the color of their hair and eyes.
So what ? आप have blond people with blue या green eyes that comes from Iran या Algeria, for example (I know a few of them), while आप expect people from these places to have dark eyes and black hair. So Severus can be like he is and still be 100% British.
Besides, he has a very fair, even pale, complexion.
All in all, skin, eye and hair color doesn't mean anything about one's origins vs citizenship/nationality.
Yeah, he is British, he was born there, so he is. But I always secretly believed him to be half Italian... He fits nicely if आप follow the stereotypes; good cook, big nose, black hair. But no he's British, but a girl can always dream can't she?
I think he is really a Britih. because his name स्रोत is UK's place name. His hair & eyes color is black, reminiscent Asian, but not only Asian's hair &eyes color is black. Maybe British has black hair & eyes color, I think. (I'm a Japanese, but I have brown hair & eyes. All Japanese people not has black hair & eyes. Some people has brown hair & eyes.)
