The concept to realize a branch export is to use "Save as" function.
Create a new file with the selected data you want.
You can use all the selections functions of Ancestris to define the data you want to export (for example, select a family group from the family group report or make and advance search and select the results).
Once you have marked the data from a way or another one, use the "Save as" and select the marked data.
Create the new file, you will have only the selected data.
Eventually, use Ancestris to adjust the remaining data if there is few data to remove.
