Ellen White

William Miller died on December 20, 1849. Almost overnight, the remnants of his church splintered over doctrinal differences. This fragmentation ultimately gave rise to a variety of denominations, including Jehovah's Witnesses and the Seventh-Day Adventists.

In the 20th century, an offshoot of the Seventh-Day Adventists updated Miller's prophecy by claiming a Biblical ETA of April 22, 1959. (Yahweh's bastard child was a no-show yet again.) This group, calling itself the Davidian Seventh-day Adventists, broke into two pieces in the resulting schism. One product of this fission decided to call themselves the Branch Davidians.
