Ada Jane Low was born in Bexley, Kent, England, and arrived in New South Wales as a two-year-old in 1857. She was accompanied by her parents, William and Emily Jane Low, and siblings, Edward and Alice, as an "assisted immigrant" on the ship Light of the Age. Two further siblings, Adelaide and Agnes, were born in New South Wales in the years that followed the family's arrival and settling in Bathurst.
Low and Watson were wed in 1889, shortly before he was elected to the New South Wales Trades and Labour Council. She was not involved in her husband's political career, except to support his decision to resign as Labor leader in 1907. She may also have been influential in her husband's later estrangement from the Australian Labor Party.
Owing partly to her husband's brief term as Prime Minister, Ada Watson is possibly the least well-known of prime ministerial spouses in Australia. No photograph of her has ever been found.
