reformed baptist denominations

Can anyone tell me the names of "reformed" or "sovereign grace" or "Calvinistic" baptist denomninations and the diferences between them (or point me in the direction on the web)?

I know that the SBC historically (?) has held to these doctrines and some Primitive Baptists?????
