Ben Affleck and Jennifer Garner’s middle child seemingly unveiled a new name Saturday during a memorial service for Garner’s father, William Garner.

During the event, the 15-year-old introduced themselves as Fin.

The teen, previously known as Seraphina Rose, dressed in a suit and tie while sporting a buzz cut.

After introducing themselves as Fin Affleck, they read Chapter 16, Verse 8 from the Book of Proverbs.

Prior to their appearance at their grandfather’s memorial service in West Virginia, Fin had been spotted rocking a pink buzz cut and hanging out with their step-sibling Emme, the 16-year-old child of Jennifer Lopez.

Jennifer announced her father’s passing over the Easter weekend with an emotional tribute shared to her Instagram.

“My dad passed peacefully Saturday afternoon. We were with him, singing Amazing Grace as he left us (did we carry him across or scare him away— valid question.) 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.”

The actress went on to thank Charleston Area Medical Center and City of Hope for “extending” her father’s life and allowing him to spend his final moments “in his favorite spots— surrounded by daughters and grandchildren, cheering for his beloved Aggies, captaining a boat, and— most of all—next to his wife of 59 years, our Mom.”

Fin Affleck is the middle child of Ben Affleck and Jennifer Garner. They have an older sister, 18-year-old Violet Anne, and a younger brother 12-year-old Samuel.
