The child's first name has a special royal connection.

The Duchess of Cambridge's sister Pippa Middleton has given birth to her second child. Pippa and her husband James Matthews welcomed their family's latest edition - a baby girl - early this morning. A source close to the Middletons told Hello! Magazine that the couple are naming their new daughter Grace Elizabeth Jane. "Mother and baby are doing well," said the source. "She's perfect, everyone is overjoyed at such a happy arrival." Baby Grace will have the same middle-name as her royal auntie, who was born Catherine Elizabeth Middleton. Pippa reportedly gave birth in the Lindo Wing of St. Mary's Hospital. The Duchess of Cambridge had her three children in that same hospital wing. Reports of Pippa's pregnancy started coming in late last year. Middleton's mother Carole confirmed the rumours when she appeared on the cover of Good Housekeeping. Carole said: "I hope to see more of my family than I could last year, including, of course, my new grandchild." Pippa is famously very private, particularly when it comes to her family. After her marriage to husband James, in 2017, Pippa stated that she was looking forward to settling down and enjoying a "quiet life". James used to be a professional racing driver but now works as a hedge fund manager. The couple have been together for six years. Baby Grace will have big brother Arthur to look up to. Pippa's first child was born in October 2018.
