Originally a short form of Germanic names such as Adelaide or Adelina that begin with the element adal meaning “noble”. Saint Ada was a 7th-century Frankish abbess at Le Mans. This name was also borne by Augusta Ada King (1815-1852), the Countess of Lovelace (known as Ada Lovelace), a daughter of Lord Byron. She was an assistant to Charles Babbage, the inventor of an early mechanical computer.
