Issac Devlin

Issac Abrams is the father of Charlotte "Charli" Abrams. He was imprisoned on various charges shortly after Charli's birth and hasn't seen her since she was six months old.

He never married Amanda Abrams, Charli's mother, though they were engaged prior to his arrest.

When Charli was fifteen, Amanda filed to have Issac's paternal rights terminated, which Issac immediately signed "for [his] daughter's sake." Charli's stepfather, Eric Abrams, then adopted Charli, giving her his last name, Abrams.
