The British royal baby has arrived and this baby boasts a diverse lineage, from Dracula to the Muslim Prophet Mohammed, reports Agence France-Presse.

The new baby was born on July 22, 2013, in London. The baby was the first royal heir to be born in 31 years-- since his father, Prince William, was born.

Royal genealogy is an interesting study for many and several genealogists embarked on the task of tracing the royal baby's lineage, even before the baby entered the world.

The baby's maternal ancestry is relatively simple. Kate Middleton, the baby's mother, comes from a long line of non-royals, or "commoners."

This doesn't mean they're poor. It just means that they don't have royal blood.

On the baby's paternal side, however, is where it gets interesting.

The British royal family comes from a long line of, well, royals.

But they're not all British royals. For one the family used to be known as the Saxe-Coburg-Gotha family, before 1917 when they chose the name Windsor. "Gotha" is essentially "Goth," which traces itself to Transylvania royalty in Romania, namely, the Princes Dracula. One of these princes was the inspiration behind Bram Stoker's "Dracula."

And now for the real surprise. In a country that has a sizable Muslim population, it's no surprise that the royal baby would also be able to trace back to the Prophet Mohammed. Genealogists have traced the baby back to the queen of France, Marie de' Medici, who is a descendant of Alphonse VI of Castilla. Castilla died in 1109 and was married to Zaida, a Muslim princess who converted to Catholicism. Zaida had ancestry that reportedly went back to the Prophet Mohammed.
