rhone
The correct spelling in French for "marron" is M-A-R-R-O-N.
There are several kinds of French; there is Parisian French from Paris, Quebec French from Quebec Canada, and French in the New Orleans area. None of these dialects need to roll the r. However, at least in Parisian French, you do have to do a "special" r, made by having the tip of the tongue on the bottom of the mouth, and arced so the middle is close to the top. It's sort of a "phlegm-y" sound, not sounding like a rolled or normal English r. It is known as "guttural R", and is used in French, Portuguese, and Dutch. Spanish and Italian (but also Indonesian) feature the so-called trilled R.
There are four phonemes in the word "river": /r/, /ɪ/, /v/, and /ə/.
Ron is a name, so it does not change when translated into a different language. Ron in French is simply spelt 'R,O,N'.
There is more than one French r. It may trilled or uvular. The uvular French or German r, incidentally, is identical to the Arabic 'ayin, a sound so foreign to English that it doesn't even have a letter, only an apostrophe.
