In a statement to People, his family said:
We are deeply saddened to share that our beloved Regis Philbin passed away last night of natural causes, one month shy of his 89th birthday. His family and friends are forever grateful for the time we got to spend with him – for his warmth, his legendary sense of humor, and his singular ability to make every day into something worth talking about. We thank his fans and admirers for their incredible support over his 60-year career and ask for privacy as we mourn his loss

Because two of Regis Philbin’s children have stayed out of the spotlight, it’s not clear exactly how many grandchildren he has. But a variety of reports indicate he has at least four grandchildren. The unauthorized biography Regis! reported that his daughter Amy had a son named Mack. His daughter J.J. has two children, according to her IMDb bio, and his daughter Joanna has one child, according to her WGA bio.

Daniel died at the age of 49 in 2014. He was honored by the Department of Defense for his contributions after September 11, 2001. Regis once said that his son Daniel was a hero to him. Regis said: “For him to overcome all this disability, to graduate from college, work on his master’s program — he’s just dynamite, a remarkable kid.”
Amy has stayed out of the spotlight, but Closer Weekly reported that she pursued a singing career at one point in her life. The unauthorized biography of Regis Philbin called Regis! reported that in the early 1990s, Amy was living in Studio City, California, with her son, Mack, and her musician husband Dan Ferguson.
He Had Two Daughters with His Second Wife
