Research suggests that this person may never have existed. See the text for details.
See this brief commentary, and the pedigree of this fictional line, that continues up the generations, for quite some time. Apparently it tries to build a case for psuedo-conjecture, by using a combination of Biblical and other ancient texts. To understand where the tree is going ... Griswald (2004), explains that:
"What is surprising is the number of different threads that exist from Abraham into Western Europe and the different paths they take. Several different threads are intertwined in the Merovingian families of Francia. Two pass from Egypt through Ireland into either Wales or Scotland. A third line comes directly from the Exilarchs (the leaders of the Jewish community in exile after the Diaspora) in Babylon. This thread goes directly into what is now southern France, where descendants married into the noble families of the region. "
However... during the 5th and 6th centuries, Hilderic of the Alans and Valans, did exist.
