I don't know if this is the first mention but the ritual of soul marrage says:

"Furthermore, the link between the two souls will not be lost even when both are dead. It is of no relevance to the undead who live together forever as husband and wife, but it is supposed that even after death their souls will never stray from one another; even if invited to the netherworld, the souls of the married couple will always stay together. It is said they will be able to become husband and wife once more if reincarnated in the next world."
