～かなんだか meaning in this sentence


I'm dealing with some TV character's lines that speak in slang.

Speaking about a snob girl, she say this to another character near to her:

> 名門 **かなんだか** 知らねえが、あのうえから目線が本当にむかつくぜ。

To me, the general meaning seems to be "I don't care if she came from a noble
family, (but) that her haughty behaviour really piss me off!", but I can't
figure out what is that "かなんだか", before 知らねえ.

May you help me to understand? Thks in advance!




> 「Word/Phrase + **（だ）かなん（だ）か** + 知{し}らない」

should be remembered as a set phrase meaning:

> "I don't care (if something/someone is) ~~ **_or whatever_** "

My own TL:

> "I couldn't care less if she's from a distinguished family or whatever. That
> arrogant attitude of hers just pisses me off."




> 「Word/Phrase + **（だ）かなん（だ）か** + 知{し}らない」

should be remembered as a set phrase meaning:

> "I don't care (if something/someone is) ~~ **_or whatever_** "

My own TL:

> "I couldn't care less if she's from a distinguished family or whatever. That
> arrogant attitude of hers just pisses me off."
