A user on Reddit r/gramps [wants to validate for christenings](https://www.reddit.com/r/gramps/comments/1j46ik9/gramplet_to_track_missing_data/) and godparents for each christening.

I can see how to filter for Persons without a christening. But how could Gramps be made to find Christening Events that lack being “[shared](https://gramps-project.org/wiki/index.php/Gramps_Glossary#sharing)” with a Godparent **role**?

With a filter similar to this one - **Baptism: Godfather or Godmother not linked to the event** (_Baptême: Parrain ou Marraine non liés à l’événement_) - based on supertool (it uses my [ST\_filters\_init.py](https://www.dropbox.com/scl/fi/omxfv2jqcwmki4i1y46n0/ST_filters_init.py?rlkey=0js4ymt0tg2dqu4u5em1ecetq&dl=0) library):

In French _Parrain_ means Godfather and _Marraine_ Godmother, _Baptême_ means Baptism.

You need to make some changes to both level 90 event filters to make the whole filter work in English, probably you just need to replace Parrain/Marraine with Godfather/Godmother in Supertool Initial statements (untested)

* * *

The Supertool filter _STF\_participant\_role_ from my library searches for events of the indicated type and whose references (Persons or Families) are of a particular role

This is very informative. Thank you.

It could be made more efficient by reducing the Role permutations so that the parameter count is reduced.

Using the [Types Cleanup Tool](https://gramps-project.org/wiki/index.php/Addon:Types_Cleanup_Tool) addon to consolidate the roles (Godmother and Godfather to Godparent; goddaughter and godson to godchild) cuts the runtime.

Probably but there is no equivalent word to Godparent in French, so I need two searches in my case
