cameo-d,
Are you looking for people who started religions that look like the WTS?
Or are you looking for all of the splinter groups that formed following his death? (Good luck if you are.)
Or are you looking for people (such as Henninges) who split from the WTS/CTR while he was still alive?
Or are you interested in showing that Rutherford was an illegitimate heir?
Or are you seeking to identify all of the heirs to Miller (1830s/1840s)?
Interestingly, just as the WTS today points (vaguely nowadays) to 1914, CTR of course pointed to 1874, a date that they kept until about 1930.
And the date that the eschatologists of the 19th century consistently pointed to was 1798.
While Miller pointed to 1843 (the 1844), others pointed to dates in the 1860s and then some opted for 1873. As you well know, Barbour, Paton and Russell opted for 1874.
Brown in 1823 (and again in 1827) pointed to 1917; Charles Wesley pointed to a date in the 1790s.
They were all wrong, so the WTS is in good company.
