The newest addition to the royal family is the seventh great-grandchild for Queen Elizabeth and the fourth grandchild for Princess Anne, the Queen’s daughter. The new baby is 19th in line for the throne.
Lena’s older sister is 4-year-old Mia, who has been charming royal watchers with her scene-stealing antics.
Lena’s birth is especially meaningful for the couple as Zara suffered a miscarriage in December 2016. Little Mia helped her parents get through the devastating ordeal.
“The saving grace for us has been Mia, our daughter who is now 3,” Mike told The Sunday Times in May 2017. “However down we feel she will come running up in our faces. When I was playing I hardly saw her; now we can see her grow up. I can take her swimming and I can take her to Ninja Tots. You’ll never be able to see her there because she disappears in a puff of smoke.”
Both Zara and Kate Middleton have seen their two families grow along similar timelines. Most recently, Kate and Zara made an Easter appearance together, when they were both in their third trimester. Prince Louis arrived 22 days later.
Lena was born at Stroud Maternity Unit in Gloucestershire and weighed 9 lbs., 3 oz., Buckingham Palace said in a statement.
