1) "on the Hudson River" or "at the Hudson River" could work, but I think they are stylistically somewhat different. "On the Hudson (River)" is more figurative, as it is used similarly with other famous rivers, e.g., "on the Nile" or "on the Mississippi", and in stock expressions like "the miracle on the Hudson". So in this case, you might want to use the figurative expression, "a bit of France on the Hudson". "At the Hudson River" seems to be more appropriate to report a state of fact, e.g., "there is good fishing at the Hudson River", even though you might also be able to describe a restaurant located "at the Hudson River". (In either case, don't forget to add the definite article.) 2) "(the) young Guillunle boys" is correct, e.g., "The young Guillunle boys were responsible for causing the fire in the barn..." "a bad, lying, smooth-talking man" is correct assuming that he is >>> a bad man & a lying man & a smooth-talking man.
