Bible Students pre-1931 organizationally always stayed away from the term "Russellites" viewing it as prejorative. My grandparents were members of the WTS pre-1931 and said they always referred to themselves as Bible Students, not followers of a man like Lutherans.
So even though they didn't like that term used for themselves, did they admit that there was a connection? That at some point their group of people were one and the same?
If so, I'm wondering when it went from "we don't like to use that term for ourselves" to "Russellites who?"
