What's the best software or site to merge datasets with lots of duplicates?

[Barly2]

Classical (stupid) problem: I've two versions of a gedcom, both now have unique and important data, but most of it is the same, not just a handful of people.

I tried GenMerge, but there are some issues (which they tell me will be resolved in the upcoming release, but that doesn't help me now).

Any tips for automated merging of duplicates, with the option to nod off or dismiss?

Hi and welcome to Rootschat...some good advice here:

Thanks for the welcome!

I've tried GenMerge, one of the tools mentioned in the link, but there were some problems - at the moment, it seems to be auto-only, so you can't tell the thing that Sebastian Duke of Deedumbia of the 13th ct isn't the same as Kevin Sebastian, born 1984, once it gets it wrong.

I use Family Historian, and have done a successful fairly-big merge. The help documentation does advise making copies of both files before doing anything else, but I didn't need to revert to the backup.

You can do it in Legacy, too, http://www.legacyfamilytree.com/; my sister has merged lots of trees with this and I have carried out a couple of merges.

Beware though that no programme is fool-proof, you must take care to check each proposed merge yourself

cheers, falcybe
