Merge genealogies (L)

This tool combines two genealogies into one.


It does not merge duplicates that might appear. See the Merge duplicates pages if you need to.


The principle of this tool is to combine two Gedcom files into one.

All the data present in the two files will be in the resulting file, with the exception of the data in the header of the second file, since the resulting file can only have one header.

The header data includes for example the format of the places, the standard used. See the Gedcom File Properties page for more details.

If data (individuals, families, etc.) is identical in each of the two files, no merger will be performed and the resulting file will contain duplicates. These duplicates can then be managed with the duplicate detection tool.

To avoid having entities with duplicate numbers which is impossible according to the Gedcom standard, the entities are all renumbered, both those of the first and the second file.



This tool is simple and works in two steps.

A first window asks you for the locations of the two starting files, and the name of the resulting file.

  • The first file must already exist and must be the one whose header data you want to keep.
  • The second file must also exist and you specify its location.
  • The third file will be created. Indicate the place where you want to place it and its name.

Then press the Unite button.

The result is immediate and a result window is displayed.


These results are used to verify that the number of entities in the resulting file are indeed the sum of the entities of the two starting files.

You can then press the left button to open the file in Ancestris and work with it normally.


There is no customizable element in this tool.
