If you're finding duplicate profiles already existing on WikiTree as you go through the GedCompare process, it's best to
- First determine which profile you believe to be using the correct Last Name at Birth (LNAB).
- If both use the same LNAB, as in your Baldwin example, determine which has the lowest ID number (i.e. Baldwin-56). That should be the remaining profile after the other one is merged away.
- From the OTHER profile -- the one with the HIGHER ID number (or incorrect LNAB), which in your example would be Baldwin-1602) -- scroll to the bottom of the profile page and select the link to "initiate a merge".
- It will ask you for the profile ID of the 2nd profile to merge into (i.e. Baldwin-56), then let you review the two profiles side-by-side to confirm they represent the same person.
- Then you can click the "merge them" link, which will prompt you to enter a comment on the profile explaining your reasons for believing they are duplicates (usually the reasons are obvious -- same name, same parents, same spouse, same children, same birth/death, etc.).
- Since there are two different profile managers on these profiles, the system allows 30 days for each of them to approve the merge. If they get it approved and the merge is completed, you should get an email from WikiTree informing you the merge is done.
- If either of them doesn't respond, then after 30 days it will open up to anyone to complete the merge, so you can complete it yourself, being careful to include the appropriate information from each profile without creating redundant information in the biography. If there's conflicting information, add a Research Note section explaining it.
- You can go ahead and match your Gedcom person to the lower-numbered ID before the merge completes, just so you can get through your process.
In the meantime, you can check other family members that the duplicate profiles link to (such as Rebecca's husband and several of his family members who are also duplicated), and propose merges for them as well, using the same process as above. Even if your gedcom won't be importing people that match them, it's a good idea to be civic-minded and propose merges for a healthier, cleaner tree.
You can always view a list of pending merges that you've initiated by going to the main WikiTree menu, select Find, then Pending Merges, then select the link for "Pending Merges Initiated by Me". That will show you the list of the merges you initiated, the date the merge was proposed, and their approval status.
Suggesting merges can seem intimidating at first, but it really isn't difficult. You mainly need to be certain that the people are actual duplicates, and not just same-named siblings (which can happen) or different generations, or same-named cousins, etc.
Hope this helps!
