To be confused about my partner's nationality

[ForestryForever]

Good evening,
My partner's parents were both born in Wales. They both lived and grew up in Wales. As adults they both left Wales and lived in England, where they remained.
Whilst married and living in England, they had a baby - my partner. My partner was born, raised in and grew up in England, and still lives in England.
What nationality is my partner?

English, if he grew up here. But also Welsh.

He’s British.

British.

English with Welsh heritage

British

English but I think he could play for Wales!

British
He's English, with Welsh heritage.

He's whichever he identifies with most.

What passport does he hold? That's your answer

He would be a British national

My grandad was from an English family, but born and raised in Wales. Had the accent and was a Welsh speaker. What is he? And then what I am?
It is confusing.
I have an ex who happened to be born in the US... had a US passport but British parents. What is he?
Arg!

What does he think it is? I'd go with that.

His legal nationality is British.

But he can call himself Welsh if he wants to.

Welsh or English, either or both really but legally British I would assume.

Partner doesn't identify with being British.
Identifies with a country, not a landmass.
I need to know if you think the answer is English or Welsh.

Surely it's whatever he considers himself to be? My mother was born in England to an Irish mother and English father. They moved to Ireland before she was three. She considers herself Irish.

He's English but I expect he calls himself Welsh.

British and then he gets to decide what he is

i know kids whose parents are the same nationality but not British - in all cases their kids who have lived here all their lives see themselves as both. Not sure what they will decide as adults

Welsh, he is first generation Welsh was born in Wales and of Welsh parents.

The Welsh would be not one bit happy if anyone accused a Welsh person of being English.

He can only be English if Welsh and English are the same thing, otherwise he’s British (Welsh).
If my children are born in Egypt it will never make them Egyptian (in the sense of having Egyptian descent).

British with Welsh heritage.
I am British with heritage from abroad.

British.

If he wants to be Welsh then he is Welsh.
If he wants to be English then he is English.

Either is correct.

It's up to him to decide.

He has dual nationality. He could play for 🏴󠁧󠁢󠁥󠁮󠁧󠁿 or 🏴󠁧󠁢󠁷󠁬󠁳󠁿 ⚽️ (other sports probably exist)

You need to ask him. What would he tell you? There's your answer.

Identity is more complex than where you grew up or were born.
