The Plymouth Brethren
Movement·Founded 1827 CE·Unknowable by design. The Open Brethren keep no central roll — assemblies are autonomous and many list themselves as no more than a Gospel Hall — and the various Exclusive connexions publish nothing except the Plymouth Brethren Christian Church, which reports just over 55,000. Estimates for the whole movement run to well over a million worldwide, heavily weighted toward India, Africa and Latin America, and none of them is from a source that counts.
