You might as well just read Livy and then read a historian's account of livy's story, because there isnt much else that im aware of, unless you count the Aeneid which was 100% bullshit.
>I'm vaguely aware that some of the kings were of Etruscan origin
we know for sure that the last three were etruscan
anthropological sources would do.
i think there might maybe be some records or something that show that tarquin and the other two existed, but im not 100% on that, nor could i tell you where to find them. i think his name mightbe written somewhere in the temple of jupiter or something like that, but again i cant remember exactly.
