Rothesteus

Rothesteus (flourished in 4th century), also known as Rothesteos, Rothestes, also Radistis was a Gothic sub-king under the Thervingian chieftain Athanaric. According to Christian Settipani, he was the father (or paternal grandfather) of Alaric I, the first king of the Visigoths, and the father of Atharid, who played a leading role in the killing of the Christian martyr Sabbas the Goth.

According to Geni Research he is the son of Hrothisteus of the Visigoths (http://www.geni.com/people/Hrothisteus/6000000009440098994)
