In February, Prince Harry and Meghan Markle announced that they were expecting their second child, on the anniversary of Princess Diana’s announcement that she was pregnant with her own second child — Harry. On Sunday, the couple revealed they were having a girl, due this summer.

Their first child, Archie Harrison Mountbatten-Windsor, was born in May 2019. Late last year, Ms. Markle wrote in an Op-Ed for The Times that she had suffered a miscarriage. In the days after Archie’s birth, Ms. Markle was praised by many for her choice to not share the details of her birth on the stairs of the hospital where she gave birth, as has historically been expected of women who give birth in the royal family.

The couple’s first date was at Soho House in London in 2016 after a friend set them up on a blind date. They married in 2018 and remained in London until late 2019. The first months of their relationship included a network of friends who helped them keep it private until the global press found out they were together. Since then, their relationship has been complicated.

Throughout the course of their relationship the couple has dealt with scrutiny from the news media, particularly in Britain where they sued the tabloids who revealed letters shared between Ms. Markle and her father ahead of her wedding to Prince Harry.
