```python
GRAMPS: AIO64-5.1.5-1 
Python: 3.6.4 (default, Jan 23 2018, 13:17:37) ... 
BSDDB: 6.1.0 (6, 0, 30) 
sqlite: 3.21.0 (2.6.0)

```

My paternal first cousins have been maintaining a family tree independent of what my parents did – there is VERY little overlap. Is there an easy way to filter out our common ancestors (which is to say our common grandparents) in the export function? Then I can just import that filtered XML file and re-link my cousins to my existing records of our grandparents.

TIA
