A number of Gedcoms that were uploaded back in WikiTree's "Wild West" days when "anything goes" seemed to be the rule include profiles for the spouse of a known person. If the known person was, say, Charlemagne, a profile appeared for "Mrs. Charlemagne."
As we've worked on profiles, often the spouse of the person was known, so we could take that profile, correct the LNAB and add appropriate, well sourced information. Excellent!
But there are other profiles, especially of pre-1500 persons, where it is unlikely the name of the spouse will ever be known, or anything about the spouse. "Mrs. King Alfred," or "Wife of King Alfred" persists as an embarassment on WikiTree.
In such cases we really need to get rid of the profile. I'm told that simply deleting a profile messes up the referral processes built into WikiTree. Given that, I propose that it become customary that as we encounter such spouses whose identity is unlikely ever to be known, to detach the spouse from children, change the gender and merge the empty profile into that of her husband.
