I know how to merge but I don' know how to do it by ID can someone help me please?
Click on the Question mark in the upper right of this web page, in the lower left of the pop up, click on "Help Center", in the search key in: "merge by id", you should get a result: How do I merge duplicates in Family Tree by ID?
I understand that you would like to know how to merge duplicate records using the ID numbers. This is a very easy process and begins in the Tools Section where there is the option to merge by ID. The following link will provide complete information and guidance.
As mentioned above, you can find answers to your questions at our Help Center.
1) Copy the ID number of the person you want to merge away.
2) Go to the person you want to merge into.
3) On the right hand side of that person's detail page, scroll to Merge by ID:
4) Click there, paste in the ID number, click continue then proceed with the merge.
Thank you all for your help 😀😀
