Jennifer Garner's family has lost their patriarch.

The Alias alum shared her father William "Bill" Garner died peacefully on March 30 at the age of 85.

"We were with him, singing Amazing Grace as he left us (did we carry him across or scare him away— valid question,)" she wrote on Instagram April 1, sharing photos of Bill throughout the years. "While there is no tragedy in the death of an 85 year old man who lived a healthy, wonderful life, I know grief is unavoidable, waiting around unexpected corners."
