It is fun to see the difference between english and french names. The pronounciation isn't even close for Theuderic --> Thierry, Odo --> Eudes, Rudolph --> Raoul...
Tho he was often drawn by cartoonist with a crown and a jest. But which president of which democratic country wasn't? (it is when cartoonist can't even draw you with a crown that you really need to wonder if this is still a republic — I am not counting the cases when the president himself is posting pictures of himself with a crown)
By that standard, Clovis is "Hlodwig", aka "Ludwig" aka "Louis".
Keep in mind that numbering was done only centuries after. So fact that, in addition to many "Clovis I", "Clovis II", "Clovis III", ... there exist "Louis I", "Louis II", isn't at all a proof that the hadn't the same name. In the registers of their days, the "Clovis" are called "Ludovicus"... the exact, letter for letter, name of "Louis Ier, le pieux", also called "Ludovicus". But, because first historians to established the list were from capetians days, they wanted to distinguish barbarians sounding names like "Clodomir", "Clovis", "Lothaire" for ancient merovingian dysnasty, and more civilized sounding "Louis" for glorious carolingians. (Same goes for Clotaire/Lothaire. Exact same names. But first historians wanted to distinguish barabians merovingians "Clotaire" and glorious carolingians "Lothaire").
So, just to say, if you insist on Chalemagne=Charles, then Clovis=Louis, Clotaire=Lothaire.
Because most of the Merovingians divided their kingdoms among their sons. So there was a King I and II but they were never kings of France (perhaps of Austrasia or other territories)
fun fact : John II was called "The Good" and in French it makes : Jean le Bon, and a common (not funny) pun with it is Jean-Bon (jambon) which means "ham".
Now btw you know how to pronounce Jean (like "jam" in "jambon")
