(Stayakarma)→Adhiratha→KARNA→Vikarna.

Adhiratha was born of Brahmin mother and a Kshatriya father according to Harivansham.

And KARNA was adopted by him.

THIS is KARNA& #39;s family& #39;s lineage which also had ancestors like King Anga and Romapada.

He was not brought up in poverty and he WASN& #39;T a Nobody.

He was the rightful heir of Anga.
Duryodhana just fastened his coronation.

His family was a Kshatriya (though his father was a Suta).

THIS is how royal Karna& #39;s family actually was.

Thanks brother @arnab_epic for providing me with the references.
