Did Dracula have any children?

Vlad The Impaler, the inspiration for the fictional Dracula character has two sons.

The Countess Ilona was invited by King Matthias to live in the Hungarian Court with her two sons after Dracula's demise. In 1508, Dracula's oldest son, Vlad, made a strike for the throne of Wallachia, but was beaten back by another relative named Mihnea who claimed to be an illegitimate son of Dracula's early days. Probably because he wanted to avoid a scandal that could hurt his mother, Vlad conceded.

If this Mihnea was lying about his bloodline, he certainly did a good job trying to act like the man he claimed was his father. The moment he set his posterior on the throne, the impalings began. But, this time the principality of Wallachia was ready. They rebelled in worthy numbers and the beast they called Mihnea the Bad was sent packing for the hills.

In the meantime, the legitimate Dracula family waned. Only Vlad lived to maturity. Of his two sons, only one married. From that point the number of direct male heirs dwindled. By the mid-1700s, the last of the Draculas was living in (where else?) Transylvania, along the infamous Borgo Pass.

Seems that Vlad also had a bit of a "Daddy Scare" during his lifetime. He dealt with this quite adeptly:

"Dracula once had a mistress who lived in a house in the back streets of Târgoviste. This woman apparently loved the prince to distraction and was always anxious to please him. Dracula was often moody and depressed and the woman made every effort to lighten her lover's burdens. Once, when Dracula was particularly depressed, the woman dared tell him a lie in an effort to cheer him up; she told him that she was pregnant.

Dracula warned the woman not to joke about such matters but she insisted on the truth of her claim despite her knowledge of the prince's feelings about dishonesty. Dracula had the woman examined by midwives, to determine the veracity of her claim. When informed that the woman was lying, Dracula drew his knife and cut her open from the groin to her breasts while proclaiming his desire for the world to see where he had been. Dracula then left the woman to die in agony."

Vlad III (Vlad Tepes) reportedly had 3 sons.

Quote:
From his first marriage, to a Wallachian noble woman, Vlad III apparently had a son, later prince of Wallachia as Mihnea cel Rău, and another two with his second wife, a relative of Matthias Corvinus of Hungary.
