Magnus Maximus, Western Roman Emperor - Lineage of Magnus Maximus (Maxen Wledig)

I do love me some Wolcott, as you know, and there are links to his studies in the Overview to this profile.

I myself think it best, at least at this time, to leave Macsen Wledig -- if indeed he is Magnus Maximus -- without parents, leaving the sources to duke it out in the Overview.
