You are right to some extent. Ludovicus is the Latin form of Louis (Fr), Lewis (Eng), Ludwig (Germ), Luigi (It), Luis (Sp) and many others. Even Ludeke in Old Low German. However, as a surname it was probably carried over from pre-Reformation times and would have no connection to given names. The "i" ending indicates either plural or Possessive (genitiv) case, meaning, in the case of names, "belonging to". This can give you almost no genealogical clue except to say that it is a very old name, and possibly not even German. However, before the Reformation many German names were Latinized (you should see some of the weird ones I've found) so it could be the result of this. (I was a trained philogilist) Jane
