I place myself here. I have used this as stated above, death of spouse, divorce, or a remarriage. On a side note, I have an ancestor who (according to undocumented family lore, which I have no reason to dispute) reportedly divorced, and then remarried the same spouse multiple times over a span of several years. I have found no documentation of the divorces or remarriages, so I have only listed the original marriage date sourced by the marriage certificate, and then listed the marriage end date when he died. Luckily, the children were all from the same spouse, so that was easy to document. The surviving spouse went on to remarry several other men, however there were no children from those unions.
