In summary

Unknown; the most popular theories are that it was either an internal innovation (from a reanalysis of the genitive in names ending with -ricus, i.e. -rici, as naming suffix) or a borrowing from pre-Roman languages (given the various forms the suffix took in the Middle Ages). Compare Portuguese -es.
