Partition Analysis

GEDCOM files are often partitioned into separate groups.
A partition is a group of folks related to each other, but not related to other folks in the GEDCOM file.

The set of folks related to each other form an "island", or partition.
Each partition is a separate genealogical tree.

To view the partitions within the GEDCOM file, use Reports ⟶ Partition Analysis ...

Partitions can be saved to produce a new file, or deleted.
Partitions can be used to divided a GEDCOM file into smaller files.

so 7 groups of people, of size 2 not related to other people in the GEDCOM file.
