Treat tragically died on June 12 following a motorcycle accident. He is survived by his wife, actress Pam Van Sant, and their two children, Gill, 31, and Ellie.

Among the photos shared by Ellie was one of her smiling as she rested her head on her father's chest while they sat together on a couch and one of the pair embracing as they stood by a dining room table.

The father-and-daughter duo sported matching black sunglasses as they sat outside at a restaurant in one throwback snap, while a more recent photo showed the pair posing together at a Hallmark channel event.

Throwback photos of Treat with Ellie as a young child were also shared in the post, including one of her sitting on her dad’s lap on a set of stairs and another as a toddler sitting on her dad’s shoulders.

Two other adorable flashback pics showed a young Ellie joining Treat onstage for a production and sitting on his lap in his dressing room while he wore elaborate face paint. A final photo showed the late actor smiling while sitting on a cart outdoors.

The poignant post comes after Ellie, Gill and Williams’ wife Van Sant, whom he married in 1988, spoke to PEOPLE this week about dealing with the loss of Treat.

"I think because of the suddenness of it — there was absolutely no preparation — so I find that I'm still grappling with the fact that it happened and that he's really, really gone," she said.

Williams’ son Gill added to PEOPLE that it feels strange to know that his father is “actually gone,” but he is grateful to see he’s “left behind this beautiful legacy.”

“I think that's something that you're very lucky if your parent is an artist — especially when [the artist] is as prolific as him, because you do get to, in many ways, still be with them through that art,” he explained.

Meanwhile Ellie noted that her father had known the value of those closest to him.

“His family was the thing that he always said [he'd be remembered for],” she said.
