My idea is that if I call the object for instance loCountries, my class can be smart enough to know that I want it to connect to the SQL table called Countries.

I am likely completely mistaken on how things work, but I can't see how an object could tell (at least at the time of instantiation) what identifier it has been assigned to (if I'm not mistaken the object instantiates *before* the assignment). I'd suggest you're probably better off passing the necessary details (e.g. table name in your case) as parameters.
