With the Duke and Duchess of Sussex expected to welcome their first child next month, speculation about the baby鈥檚 name is at a fever pitch with at least one genealogy company claiming to have come up with the top contenders.

The online genealogy company Ancestry has released its top three name predictions for if the infant is a girl and another three if the child is a boy.

The company said its genealogy historians and experts combed through 鈥渉istorical records鈥 and 鈥渘aming traditions鈥 to determine the most likely names for the little royal.

If the baby is a girl:

Lily 鈥 Ancestry said Prince Harry and Meghan might select the name Lily in honour of the Queen. The company said the name would be a spin on the monarch鈥檚 nickname 鈥淟ilibet.鈥

Ruth 鈥 Another strong contender, according to Ancestry, is the name Ruth. Both Prince Harry and Meghan have great-grandmothers named Ruth so the company said this could be an option.

Matilda 鈥 The genealogists proposed Matilda as another possibility because it鈥檚 a historically popular name with the Royal Family.

If the baby is a boy:

Charles 鈥 This is a fairly obvious choice by Ancestry鈥檚 historians who said Charles might be a good choice given the couple鈥檚 close relationship with Prince Harry鈥檚 father Prince Charles.

Philip 鈥 Although Philip was a more popular choice for the baby鈥檚 middle name, experts also selected it as a possibility for the baby鈥檚 first name. Ancestry said the Duke and Duchess of Sussex 鈥渨orked very hard鈥 to win over Prince Harry鈥檚 grandfather and they are expected to honour him in some way.

Alexander 鈥 Ancestry said Alexander was included in the list because of the name鈥檚 popularity throughout history. The company called Alexander a 鈥渃lassic royal name鈥 much like Henry, Prince鈥檚 Harry鈥檚 real name. The name also has a 鈥渞elatable, more relaxed nickname,鈥 according to the experts.

The baby鈥檚 full name:

In addition to predicting the Royal Baby鈥檚 first names, the genealogy company suggested several middle names for the child.

If the baby is a girl, Ancestry suggested Louis, Diana, and Ann as possible middle names. For a boy, the company said Philip, Alvin, and Thomas might be good picks.

As for the baby鈥檚 name in its entirety, the experts鈥 most popular choice for a girl was Lily Janette Windsor followed by Ruth Ann Windsor.

If the baby is a boy, Ancestry proposed Charles Alvin followed by Charles Philip Spencer as likely options for the child鈥檚 full name.
