The Spanish etymology of the word may mean “wild hog,” and that might explain the origin of boar heads used in the family crests of families with the root of Maron/Moron. Historically, being a Maroon was a source of pride. Those familiar with fairy tales will obviously not overlook the use of three boars on the crest.
However, the etymology of these family names also hints at them having been followers of a possibly “red haired” or “red colored skin” hero or saint called Ruan.
There is a potential misspelling that might imply Milesian connections, but that could not be verified as the name was not found in additional sources.
