Dynastic sealings

What the numbers show

Adoption was not a metaphor and it was not permanent. Men took their adoptive father's surname, farmed his land and called him Father — and some of those bonds were formally cancelled, while the whole practice was abolished within a single lifetime.

Could an adoption be undone?

YES, but distinguish two things. A handful were FORMALLY CANCELLED. Far more simply LAPSED - Stapley writes that after the exodus the adoptive relationships 'quickly attenuated, then disappeared', without anyone dissolving anything.

The cases we can document

No overall count exists. No overall count of cancelled adoptions exists in the sources consulted. Do not put a number on it.

Things worth knowing

Where to read more

This whole section rests on Jonathan A. Stapley, "Adoptive Sealing Ritual in Mormonism", Journal of Mormon History 37:3 (2011), and on John G. Turner's Pioneer Prophet. What the vocabulary meant is set out on the doctrine page; the ritual's end in 1894 is on the chronology, where dynastic sealings can be filtered on and off.
