His touching and funny speech highlighted how his wife, Jazz Charton, said she’d have another child with the star as long as he won an Oscar. Family-growth plans aside, Culkin also thanked members of his own family – including his parents Kit Culkin and Patricia Brentrup, giving a specific shout-out to the latter. 

However, his famous sibling Macaulay was noticeably absent and it got many fans wondering about their relationship.

First off, yes Kieran Culkin and Macaulay Culkin are related. Kieran is the fourth of seven siblings and Macaulay’s younger brother.

Kieran’s siblings include 48-year-old Shane, 44-year-old Macaulay, 40-year-old Quinn, 37-year-old Christian and 35-year-old Rory. The Culkin brothers’ sibling Dakota was born in 1978 but sadly passed away following a car accident in 2008. She was 29-years-old.

Macaulay shot to fame as a child actor throughout the early 1990s, famously starring in 1990’s Home Alone and its 1992 sequel Home Alone 2: Lost in New York. Rory is also an actor.

Kieran and Macaulay famously starred alongside each other in Home Alone and its Big Apple-set sequel. Macaulay played abandoned kid Kevin McCallister with Kieran playing his on-screen sibling, the bed-wetting Fuller.

According to quotes given by Kieran, the pair do seem to be as close as many regular siblings. When asked about his brother live-tweeting his appearance at the Golden Globes in 2019, Kieran said “Oh man! I haven’t seen that. I’m on no social media, so I did not see any of that.”

He also commented on his brothers support, saying “Because family. That’s easy, right? I mean, you got family.”

Macaulay has seemed very supportive of his brother’s newfound success. He even joked about it when his Succession character started to gain traction with critics and awards shows.

“Oh s—t! My brother is at the Golden Globes?! That is so cool,” he tweeted in 2019. “HOLY S—T KIERAN IS NOMINATED??? WHAT IS SUCCESSION?! Man, I should really answer his calls more often. Thanksgiving is going to be really awkward this year.”
