I just refer to your link to Wikipedia. The çurrent version of Jehovah's witnesses dates back to 1931, and even by then they no longer believed in much of Russell's ideas. So to claim they started in 1870 is a bit far fetched..isn't it ?
Of course..now the current catalogue of beliefs is different to what they taught in 1931..so..yes..they are very much a splinter group from the Russell era.
