In order to try and establish a credible line of former brethren who had the same beliefs as Christadelphians prior to John Thomas, some Christadelphians have searched though historical records and selectively represented those beliefs of theirs which agree with them. The most prominent examples of this are two books The Protestors and Brethren in Christ written by Alan Eyre.
Another Christadelphian, Ruth McHaffie, finding in her own research contradictions, and unhappy with the intellectual dishonesty, comprehensively researched all the people presented as former brethren, and found the following list to be amongst their beliefs not mentioned. It is taken from a booklet called Brethren Indeed (p. 32) which summarises the findings of her book, Finding Founders and Facing Facts which is currently out of print.
If these people presented as brethren were alive today they would be disfellowshipped for holding such beliefs, but the claims there are antecedents to Christadelphians within history continue, and are frequently claimed on Christadelphian websites despite the lack of any substantive evidence.
