Could WikiTree be made to automatically detect consanguine marriages and double in-law marriages?

Question

When a marriage is created, and the parents, grandparents are known these types of marriages could be detected and flagged, perhaps by adding the relevant categories to all profiles involved.

Why? "Flagged" might be taken as having a negative connotation. Such cases should be treated sensitively by human judgement, not automatically in some blanket way by software.

I don't think of "flagged" as negative. Marked as interesting, using some term that people don't see as negative.

Answer 1

Note exactly what you are asking for, but I note that, for any person with a profile on WikiTree (eg you), the Ancestor Explorer app will identify all ancestors of that person whose parents were related to each other by blood (provided that the common ancestor of those parents is within the number of generations covered by the list of ancestors (up to 25 generations)).

If any list of ancestors going x generations back shows pedigree collapse (ie the person's tree going x generations back contains the same person more than once (a "duplicate" ancestor) because the same person is the ancestor of more than one other ancestor), a sentence will appear immediately above the list of ancestors that says "Click here for a list of the instances where an ancestor's parents were related to each other, causing the duplicates in the list." Clicking on the link will show a page with a table that shows all instances where the parents of an ancestor were related to each other through a common ancestor, the degree on consanguinity between the parents, and the number of duplicate ancestors in the tree resulting from each such instance.

Thanks, that does find the example that I knew of, in my direst line. However it doesn't find another example, not in my direst line, so I'd have to specify one of their descendants to find that. I.e I have to have a suspicion of consanguinity first.

I was looking for something that would find it when I didn't suspect it.

Answer 2

Actually, siblings marrying siblings has a category that can be added to the relevant profiles: Double In-Law Marriages .  Would not try to make it automatic, as all relevant profiles may not be created at the same time.  As for consanguinity, since there are varying degrees of such, don't see the point of it as a tag of any sort.
