I'm surprised to see the Brethren/Mennonites under the Calvinist heading. Some of the most strident anti-Calvinist tracts I've ever seen came from a Bretheren church. But everything gets rather mixed up these days.
J.N. Darby, the founder of the Pllymouth Brethren was a calvinist. Today many are only "moderate" Calminians.
The Mennonites are Anabaptists by heritage and certainly not Calvinistic.
