Genobaud was a leader (dux) of the Franks. He invaded the Roman Empire in the year 388, and worked alongside Marcomer, and Sunno. They are not related, and none of them have any documented relatives. But false genealogies started cropping up during the 8th century, and then again during the 1400s.
See this brief commentary, and pedigree of Genebaud's fictional line. It continues up the generations, for quite some time. Apparently it tries to build a pedigree on 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. "
For the curious... the FICTIONAL tree technically terminates with the Biblical Abraham and Sarah, at the top; and Clovis I at the bottom.
