http://www.abcgenealogia.com/Godos00.html has an "interesting" genealogy of the Visigothic kings in Spain, connecting, by direct descend, Theodoric "the Great" with the subsequent kings down to Rodrigo, last king of the Visigoth who died in 711 during the conquest of Spain by the Moors. It does not list any sources. Internet searches on the genealogy of Visigothic kings in Spain show that this link is the source of multiple other documents.
http://fmg.ac/Projects/MedLands/VANDALS,%20SUEVI,%20VISIGOTHS.htm#_Toc340918293 is fully documented with primary sources and not only indicate that the line has broken multiple times, but also has a different list of kings.
Anyone knows where abcgenealogia got their list or why it is reference as an authority?
