Ancestry claims Radu's ancestry is uncertain. During his life, Radu claimed to be the son of
Radu Mihnea, but other versions of his history give different accounts of his ancestry, such as claiming his true father was
Radu Șerban or
Mircea Ciobanu.
Pârvu Cantacuzino claims that "Mihnea was originally a
Greek money-lender. His father was called Iane the Deaf (Rom. “Surdul”), and he himself was baptized Franți. Thus, showing from a young age a propensity to follow Ishmael, Hagar's son, he ran away from his parents, went to
Țarigrad, and bowed in allegiance to Kinan-pașa, telling him that he was the son of Radu-voivode and the grandson of Mihnea-voivode. And thus he spent his life with the Turks, around 40 years". ==Biography==
