what are the parameters which joins family members

Question

How does the system find/join the ancestral grand father from mother side and father side who happen to be the same person.

As a point of fact in my case .. my great-great-great-grandfather (maternal) and great-great-great-grandfather (paternal) is the same person

Answer 1

Build a profile for each of your ancestors as individual people - one profile per person who lived. Then connect the profile ID of your great-great-great grandfather to each of his children while also connecting the correct mother to each of those same children. If every person on your tree has the correct biological parents connected to him, the tree will be correct - even if the same person appears on both your maternal and paternal branches.

I will defer to one of the more experienced members of the DNA project about how the relationship you've described effects the "verified by DNA" tools. www.wikitree.com/wiki/Relationship_Finder_for_Genetic_Genealogy

Thanks,

But it seems complicated , primarily say i have imported a gedcom and my cousin brother has imported a gedcom ,, and in both cases say it s 5 generation.

So the question is there will be lot of identical data points (and at this point let us not bring DNA code), so how does the system identify the identical entries and offers to merge besides profile-id (which is not practical)

Instructions for uploading Gedcom files are located here

www.wikitree.com/wiki/GEDCOM

It has been quite a few years since I've uploaded mine. I do, however, remember that part of the process is to review a spreadsheet generated by the system (called GEDCompare) of potentially duplicated profiles for the same person - ie. A person on your Gedcom file already has a profile in Wikitree. You manually decide if the two profiles are the same person, in which case you un-check that person on your Gedcom so they are not added again, or you allow the upload because, although very similar in data set, the two are actually different people.

GedCompare is a good tool , how ever if i just remove the duplicate , the underlying connectivity to the siblings is gone

Just the two parameters seems to be the deciding factor it is rather archaic i think 

quote from gedcompare "It only considers names and dates. It does not take into account locations and family relationships. If no dates are included for a person, it won't find any matches."

Why would you say WikiTree ID is not practical?  I'm not sure how WikiTree actually stores the information for a profile, but it needs to have some unique absolute piece of inform.  relationships just won't work.  WikiTree then makes one of several sort of "connections" which create the relationships.  This means that if a connection has to be changed by later information being found, only that one connection changes but the relationshiips change in a natural way.  I think the only connections tracked on WikiTree are parent-child and "spouse".  Though any number of other relationships can be expressed via the Biography.

On this forum, we are geneaologists. We can help you create your tree or upload one you have created. We can help with source citations, style and content. We can even help with user-level questions about how to use the system.

If you wish to discuss the relative merits of the logic used in creating the database, I suggest you message the Sysops with a request to speak to the programmers. The address is info@wikitree.com
