It's fairly common for names of places, especially places of great historical importance, or areas where multiple cultures have traditionally overlapped, to have variant names in different languages. There's nothing really odd or strange about this, and Trois-Rivières/Three Rivers is a trivial example, in which the translation is directly obvious. There are plenty of other examples that are a bit more confusing, especially where German place names are concerned; see Bratislava/Pressburg or Aix-la-Chappelle/Aachen. Calling San Francisco "St. Francis" is strange because "San Francisco" has become the standard English name of that city, which doesn't seem to be the case for Trois-Rivières/Three Rivers - the very fact that no one ever says "St. Francis" but the author of this blog did use "Three Rivers" is evidence of this.
