THANX, Steve, but I'm going to follow Helen's advice ... for now, at least ... which means leaving the start and end dates as they are. After all, the marriage did legally exist for the 4 days from when it occurred until when it was voided ... it's only after the void date that it ceased to exist and retroactively changing the fact of its existence is way beyond WikiTree's capability or even - probably - any reasonable desire for expansion of capability! Looking at what I just wrote makes me scratch my head and think that what I just described is probably more like annulled, but I'm neither a lawyer nor an English major, plus this isn't my family and I plan to orphan all these profiles after I finish what I can do for them, so I'm not going to bother my silly head about it anymore.
Helen, why oh why didn't you make your comment an answer so that I could select it??????
PS I'm also going to leave the non-conforming use of the location field with the appended identification of the marriage as voided. Someone else is more than welcome to come behind me and change it and I can well understand the rationale for doing so - I did put the correct location in there, as well as tack on the void piece at the end of it, plus I explained the situation fully in the biography.
