Rob Kardashian - The male sibling in the Kardashian empire has always famously stayed out of the spotlight, until his complicated relationship with the mother of his daughter, Blac Chyna, threw him right under it in 2017. Now that they’ve split, Rob has disappeared again and everyone proceeded to forget he exists.

Donnie Wahlberg - The actor and musician is also Mark Wahlberg’s older brother, but his case is unique. He was actually a big hit as a founding member of the boy band ‘New Kids on the Block.’ But as time passed, we all sort of forgot about him and paid more attention to his younger brother.
