Ada had worked for several years as an elementary school art teacher and was a member of the Augusta Art Guild.
She was married to husband Kenny and led a private life – though supported her brother publicly over the years, including attending his wedding to wife Amal in Venice in 2014.
Ada was snapped standing next to Clooney on a boat as they rode along a canal in the city.
The siblings grew up together in Kentucky and are said to have been very close.
