Re: GEDCOM Duplication

Yes, it advises that you import the MyHeritage GEDCOM into FH as a New Project.

If you have Media that needs to migrate into FH then use the MyHeritage Family Tree Builder rather than the Online Family Tree.

See the Knowledge Base for Importing from MyHeritage and follow all its advice:


Practice using the File > Merge/Compare File command on a copy of your main Project and a subset of MyHeritage data.

The most common mistake users make is forgetting to check EVERY TAB for each type of record in the Merge dialogue.

If you follow the advice carefully then you should avoid any disasters, but if they arise then there is a recovery path using backups.

Thank you, Mike.  For the avoidance of doubt, will the procedure in the link you gave avoid or help to avoid the disaster of which you warned?


Yours aye,

Hi Geoffrey

FH has a File > Merge/Compare File command, but there are many pitfalls in using it successfully.

There are options for automatically synchronising duplicate records (not just Individuals but also Sources, Media, etc.)

Do NOT try and merge a GEDCOM file exported from MyHeritage directly with your main Project as that spells DISASTER.

There is much advice in the FUG Knowledge Base in the Merge/Compare File section:


I suggest you join the FHUG and review the advice before proceeding, and ask any further questions in the Forum there.

I wish to align my FH project with a MyHeritage project that is rather larger.  Please tell me, if I seek to transfer a GEDCOM file, how does FH resolve large numbers of duplications?
