First, let me say I have tried to figure this out by myself. I have googled, searched and read posts. No success and much frustration.
I am on a Macbook Air, version early 2015, RootsMagic version 126.96.36.199.
I have been using TMG for several years and switched in January to RootsMagic. The learning curve is steep, but I'm figuring most things out.
What I can't figure out is how to either "merge" duplicates into one person, or delete the "extra" person. I downloaded my tree on Ancestry in gedcom form and imported it into RootsMagic. This increased my normal person count by over 3000. So I have 3000+ duplicates.
I ran all the data base utilities, I ran the automatic merge. No help. I discovered I can manually merge and delete individually, but with over 3000 I'm hoping there is a better way.
