Avabai, Lady Jeejeebhoy (born c.1793) was the wife of Sir Jamsetjee Jeejeebhoy, 1st baronet. She is best known for having funded the construction of the Mahim causeway in Mumbai (Bombay), which serves today as an important link between the island city of Mumbai with its north-western suburbs.
Avabai was born the daughter of Framji Batlivala, a Parsi merchant of modest means who carried out a trade in bottles in the Fort area of downtown Mumbai (Bombay). The family belonged to the Parsi community. As per Indian custom of that era, Avabai was wed at age 10 to the 20-year-old Jamshetjee, who had lost both his parents at a young age and was then venturing his first foray into commerce under the tutelage of Avabai's father. Jamshetjee was Avabai's first cousin, being the son of Framji's sister Jeevibai. The couple enjoyed a marriage of great felicity and were the parents of seven sons and three daughters; however, four sons and two daughters succumbed to the dangers that plagued infancy in the 19th century.
As a merchant, Jamshetjee enjoyed success far beyond his expectations and accumulated a vast fortune; by some estimates, he was worth a stupendous two crore (twenty million) rupees by age 40. Both he and Avabai were unstinting in their philanthropic efforts and are credited with funding as many as 126 different public charities. In recognition of these services to the public good, Jamshetjee was conferred a knighthood in 1842 and Avabai become Lady Jeejeebhoy. Subsequently, in 1857, a baronetcy was conferred upon Jamshetjee.
Before 1845, there was no connection by land between the present-day Mumbai neighbourhoods of Mahim and Bandra; people had to be ferried across the Mahim Creek. This was dangerous during the monsoons, when the seas around Mumbai are extremely rough; people sometimes lost their lives merely in crossing between Mahim and Bandra on the ferries. The passage of carriages and other vehicles was impossible and separate arrangements for conveyance had to be made on either side.
