Wt doesn't like the answer to your question. Just work backwards from russell. Russell got his stuff from the adventists, who were started by william miller, who was a baptist. Baptists can supply a lineage going back to first century christianity.
Clipped from the site below is the claimed baptist lineage to the first century. I reversed their order so that it goes from the most recent to the oldest.
Step IX -- In parts of Europe the Anabaptists were called Mennonites, a name derived from Menno Simon who was converted to the Baptist faith from the Catholics in 1531. Turning from the Catholic priesthood, he drew a great following of Baptists after him, whom his enemies called Mennonites. Those Baptists were the predecessors of the English Baptists.
Orchard wrote: "It was in 1536, under Menno, that the scattered community of Baptists were formed into a regular body and church order, separate from all Dutch and German Protestants, who at that time had not been formed into one body by any bonds of unity . . . The Mennonite Baptists consider themselves as real successors to the Waldenses, and to be the genuine churches of Christ" (Op. cit., 368).
From the British Isles, Baptists came to America in the early part of the seventeenth century. There is a clear succession of Baptists from Palestine to America.
Some other names by which Baptists have been known through the centuries are Cathari, Bogomils, Paterines, Petrobrussians, Henricians, Arnoldists, Berengarians, and Catabaptists.
Step VIII -- Even though Baptists were called Anabaptists as far back as the second century, because they re-immersed all who came to them from any irregular or alien group, it was in the sixteenth century that their cause was made prominent under that name. It was a great evangelical movement. The genuine Anabaptists were the same people as the Waldenses.
Step VII -- The appellation of Waldenses was also applied to Baptists from the twelfth century to the Reformation of the sixteenth century. Apostolic in origin, the Waldenses were found in the second century in the Piedmont Valley of Northern Italy. From "Valdenses," meaning valley dwellers, they got their title. By the twelfth century they had grown to be numerous and powerful, spreading over France and into all the countries of Europe. Because of their sterling character and fidelity to the simple gospel faith, the Waldenses suffered dreadful persecutions. Orchard, after saying their views were one with those of the Baptists, declared: "The Waldenses were, in religious sentiments, substantially the same as the Paulicians, Paterines, Puritans, and Albigenses" (Ibid., pages 258, 259).
Dr. Armitage quoted Mosheim and Limborch as marking the likeness of the Waldenses and the Baptists of the sixteenth century.
Limborch said, "To speak candidly what I think, of all the modern sects of Christians, the Dutch Baptists most resemble both the Albigenses and Waldenses" (History of the Baptists, by Armitage, page 304).
The Waldenses were the predecessors of the true line of the Anabaptists of the sixteenth century and the people now called Baptists.
Step VI -- From the tenth to the middle of the thirteenth century Baptists were called Albigenses, deriving that name from the small city of Albi in Southern France, which became the center for those people. Some historians hold them to be descendants of the Paulicians who came from Armenia to settle in France and Italy. Other historians have found traces of them which show that they had been "in the valleys of France from the earliest ages of Christianity. They were a people of reputable character and were very numerous, numbering eight hundred thousand in the twelfth century" (A Concise History of Baptists, by Orchard, page 188). They taught doctrines now held dear by Baptists,
Step V -- The name Paulicians was applied to Baptists in the seventh, eighth, and ninth centuries because they earnestly contended for the teachings of the Apostle Paul.
Dr. John T. Christian declared: "The Paulician churches were of apostolic origin, and were planted in Armenia in the first century" (A History of Baptists, page 49).
The Paulicians became prominent and powerful in Armenia in the middle of the seventh century. They taught doctrines held by Baptists of today. Brockett said: "The Armenian Paulicianists were clearly Baptists" (Jones' Church History, page 245).
Step IV -- In the fourth, fifth, and sixth centuries Baptists were called Donatists. That name originated in A.D. 311. It was taken from a prominent leader, Donatus of North Africa, who both denounced Catholicism and defended the purity of the faith.
Fuller, an Anglican historian of England, said: "The Anabaptists are the Donatists new dipt."
Osiander testified: "Our modern Anabaptists are the same as the Donatists of old."
Bullinger wrote: "The Donatists and the Anabaptists held the same opinion."
The Montanists, Novatians, and Donatists held the same fundamental beliefs and enjoyed fellowship in places where they met. In all essential respects they were Baptists.
Step III -- In the third and fourth centuries Baptists were dubbed Novatians, from Novatian who rose against the corruptions of the church at Rome. Fusing with Montanists, the Novatians extended throughout the Roman Empire.
"The Novatians demanded pure churches which enforced strict discipline, and so were called Puritans. They refused to receive the 'lapsed' back into the churches, and because they held the Catholics corrupt in receiving them, they re-immersed all who came to them from the Catholics. For this reason alone they were called 'Anabaptists,' although they denied that this was rebaptism, holding the first immersion null and void, because it had been received from corrupt churches" (History of the Baptists, by Armitage, page 178).
Step II -- Baptists were called Montanists in the second century. The name originated in Phrygia from a prominent leader named Montanus who avowed the Christian cause that had spread over Asia Minor and other regions of the Roman world before the close of the first century. "The Montanist churches were Baptist churches" (Church Perpetuity, by Jarrell, page 76). The great Tertullian identified himself with those people.
Step I -- The Scriptures support the declaration that the Christians of the first century were Baptists. Dr. John Clarke Ridpath (a Methodist), historian of DuPaw University, said: "I should not readily admit that there was a Baptist church as far back as A.D. 100, though without doubt there were Baptists then, as all Christians were then Baptists" (Church Perpetuity, by Jarrell, pages 58, 59).
Of course the catholic church can do the same.
