Technically there are only three Protestant Churches: Lutheran, Anglican (CoE), and Presbyterian (Dutch, French, or Scots Reformed). They "protested" and eventually came out of the Church of Rome.
The others did not protest and come out of the Church of Rome but came out of the churches which came out of the Church of Rome.
Methodists came out of CoE.
Wesleyan our of the Methodists.
Congregationalists came out of CoE.
Pentecostals out of Wesleyans.
Evangelical Free Church out of Lutheranism.
Unitarian Universalist out of Presbyterian
Baptist are not Protestants in that they were never in the Church of Rome, never Protested it, never tried to Reform it, and never had to come out of it.
But some Baptists came out of the CoE while others trace their roots through the various anabaptist groups on the continent.
The Particular Baptists under John Spilsbury, who was a Separatist (Congregationalist), are 3rd generations removed from the Protestant Reformation.
The General Baptists, under John Smyth, who had been an Anglican (CoE) clergyman who was influenced by the anabaptists and left the CoE and became a "Se-Baptist" (one who baptized himself). In later life he regretted doing so and sought baptism from a Mennonite group (anabaptists). For doing so he was excommunicated from his Baptist church by then pastor Thomas Helwys. Smyth eventually drifted off into confusion and denial of original sin and other bible doctrines.
