Mukesh Dhirubhai Ambani was born on 19 April 1957 to Dhirubhai Ambani and Kokilaben Ambani. He has a younger brother, Anil Ambani, and two sisters, Dipti Salgaoncar and Nina Kothari. The Ambani family lived in a modest two-bedroom apartment in Bhuleshwar, Mumbai until the 1970s. Dhirubhai later purchased a 14-floor apartment block called 'Sea Wind' in Colaba, where, until recently, Mukesh and Anil lived with their families on different floors.
