Roman Abramovich has named his new son Aaron Alexander Abramovich after his late father Arkady, whose Jewish name was Aaron.

Mr Abramovich's father was killed in a construction site accident in Russia when the billionaire Chelsea owner was just four years old.

Daria Zhukova gave birth at Los Angeles’ Cedar-Sinai Medical Center last Thursday. The hospital is close to where the former model grew up and her Jewish mother Elena’s home. Ms Zhukova attended a Jewish school in California as a teenager.

It is not known whether Aaron has yet had a brit, but Ms Zhukova recently told The Guardian that Judaism is “the religion I connect with most”. The baby is also named after her father, the oligarch Alexander Zhukov, who is a practicing Christian based in London.

Mr Abramovich, who was by his partner’s side as she gave birth, has recently shown signs of moving closer to his Jewish roots. One of his five children from his second wife, Irina, is named Arkady.
