Hannah had used her mother's maiden name on her social media for years before she legally made the change.

Hannah (right) chose a combination of her mother's maiden name and her husband's surname after she got married On social media, sports rosters, email and restaurant bookings, she was Hannah Leonard, sharing her surname with her mother. But legally, and at work and school, she had a different surname - the one she inherited from her father. Hannah's parents divorced when she was a toddler and she hasn't had much of a relationship with her dad since. She says she last saw him seven years ago and isn't sure where he's living now. Last month, the 25-year-old in California legally changed her surname to Leonard-Ripley, removing the reminder of her father and replacing it with a name combining her mother's maiden name and her husband's surname. That same month, two of the adopted children of Hollywood divorcees Angelina Jolie and Brad Pitt undertook an important legal step in the process to drop their father's surname, something they began earlier this year. Angelina Jolie with her children Zahara Marley Jolie-Pitt and Maddox Chivan Jolie-Pitt In April, Zahara Marley Jolie-Pitt and Maddox Chivan Jolie-Pitt, aged 21 and 24, filed documents to remove their father's surname from their names, according to media reports.
