Hi Richard,

I think you are asking how to merge part of your friend’s tree into your tree.

You first need to create a Project or a GEDCOM extracted from your friend’s tree that contains the direct line you want to transfer.

Either:

1. Use File > Project  Window > More Tasks > Copy Project to make a copy of her project.
   Then use File > Split Tree Helper on the copy to prune it down to the records you want to transfer.
   
   

OR

2. Use File > Import/Export > Export > GEDCOM File and <<Select the Individuals you want to transfer.

In both cases, there is a technique for selecting Individuals from a tree Diagram and using that list to choose what to transfer.;

See FHUG Knowledge Base ‘Create an export GEDCOM based on a diagram’

https://fhug.org.uk/kb/kb-article/create-an-export-gedcom-based-on-a-diagram/

In your case, you might only select the direct line ancestor boxes in the Diagram.

The resulting Name List can be applied to either the Split Tree Helper or Export > GEDCOM File method.

After creating the pruned Project/GEDCOM, use the File > Merge/Compare File command to import those records to your tree.

There is advice in the FHUG Knowledge Base on the Split Tree Helper, Export > GEDCOM File, and Merge/Compare File commands.
