Patti Davis
Patti Davis, the daughter of former President Ronald Reagan, was already an adult by the time her father was inaugurated in 1981. At that point, Patti had already begun her acting career and had appeared in guest-starring roles on The Love Boat, CHiPs and other TV series.

Patti's relationship with her Republican father was reportedly strained, as she was very vocal about her opposing liberal beliefs, but she reconciled with both of her parents as she approached age 50 and her father's Alzheimer's disease worsened. She even wrote a memoir about her father's progressing dementia, The Long Goodbye, and is the author of eight published books to date.

Today, Patti lives in Los Angeles and works as a writer.
