Seven key facts about David Cassidy, from his birth to his final days.

Why did David Cassidy leave his daughter out of his will?

David Cassidy’s will, filed in 2018, excluded his only child, Katie Cassidy, a fact that shocked many fans. The New York Times (major daily newspaper) reported that the document left his estate to his wife of 25 years, Sue Shifrin, and his half-brother. Katie Cassidy, an actress known for Arrow, was not mentioned.

Why didn’t David Cassidy have a relationship with his daughter?

The estrangement reportedly began in the early 2000s. According to People (celebrity news magazine), Cassidy and his daughter grew apart due to his ongoing struggles with addiction and his refusal to seek help. Katie has rarely spoken publicly about their relationship.

• Cassidy admitted in a 2017 interview that he had not been a good father and that his daughter had “every right” to be angry.
• A source close to the family told BBC News (UK broadcaster) that the relationship had been “strained for years.”

The implication: The emotional neglect David suffered as a child became a template for his own parenting, making the estrangement from Katie Cassidy not an isolated incident but the culmination of a family legacy of pain.

Was Jack Cassidy nice in real life?

Jack Cassidy, David’s father, was a successful Broadway actor but, by multiple accounts, an abusive and absent parent. Wikipedia (community encyclopedia) notes that David described his father as “violent” and “unpredictable.” Jack’s behavior likely shaped David’s own struggles as a father.

“I didn’t recognize the person he had become. It was heartbreaking.”

• Cassidy’s mother and grandfather also had dementia (MLive (Michigan news outlet))
• He told Biography.com (online reference) that he had “no signs of dementia” at the time of the interview, attributing his symptoms to alcohol poisoning
