NEW DELHI (AP) — In a season of big Indian weddings, the Wednesday marriage of two business scions is set to be the biggest of them all. The bride, Isha Ambani, is the Ivy League-educated daughter of industrialist Mukesh Ambani, thought to be India's richest man. Forbes estimates his net worth at over $43 billion. The groom, Anand Piramal, is the relative pauper. His father, industrialist Ajay Piramal, is thought to be worth $10 billion.
