Meaning & History
Latinized form of Reinier, but not a proper latinization when one takes into account the spelling rules of the Latin language (and therefore, understandably, Reinierus is the least common form out of all the possible latinizations for Reinier). The proper latinized form is Reinerus, and thus one could consider this name to be a variant spelling of that name.
