I think the Seven Rings were common enough knowledge, at least amongst Erebor's in crowd. Isn't it Gimli that says each of the Great Hoards of old had at their foundation a Ring of Power?
I would hazard a guess that yes, Thorin did know about his father possessing a Ring of Power, and also knew that it had been borne by the ruler of Durin's House ever since that nice Annatar fellow gave it to them. The passing on of a Dwarf Ring is a whole 'nother kettle of fissh.
Would the bearer have the strength of will to pass it on to the next generation? Or would Thráin have removed it from Thrór's still-warm finger when he died? Did they lengthen lifespan the way that the rings of the Nazgûl did? Or did the Dwarves never wear them, preferring to remain visible? And how cool is that John Howe picture??
