Prince Harry and Meghan Markle may name their baby “Diana.”

There are rumors that the Duke and Duchess of Sussex might use the late Princess of Wales’ name for their firstborn. Betting odds suggest that the name Diana soared to 10/1 ahead of Victoria, Alice, Grace and Albert.

“Victoria may be favourite in the betting but it's Diana who is running away with things in the popularity charts for Harry and Meghan's firstborn,” Ladbrokes' Alex Apati said.

It’s also possible for Prince Harry and Markle to choose a unique and non-traditional name. Prince Harry is already sixth-in-line and his upcoming child is further down the line of succession.

“We see, from the diversity of names among the Queen’s descendants, that the Queen does seem willing to allow the descendants to choose their own names,” Carolyn Harris said.

Prince Harry and Markle’s baby will have a different role from Prince William and Kate Middleton’s children: 5-year-old Prince George, 3-year-old Princess Charlotte and 8-month-old Prince Louis. Also, the baby is unlikely to have a royal highness prince or princess title.

Just like Prince Harry’s cousins Princess Beatrice and Princess Eugenie, his baby is expected to not carry out full-time royal duties. The Duke and Duchess of Sussex’s child will have to work for a living.

The palace announced Prince Harry and Markle’s pregnancy during their Commonwealth tour in Sydney. It didn’t specify how far along the “Suits” actress is and only stated that the baby is due in spring 2019, which will start on March 20 and end on June 21.

According to Jane Mayhead, senior trichology consultant at the Private Clinic of Harley Street, Markle is already in the six-month mark due to her appearance. Based on Markle’s photos, she tends to have thicker locks.

The increased levels of hormones during pregnancy caused the growth cycle of the hair to increase so a pregnant woman will have thicker and shinier hair, Mayhead explained. Considering this observation, Markle may give birth to her first child in March. On the other hand, betting odds suggest that Prince Harry and Markle will welcome their child in April.
