I don’t know how translation works in this case. The local names are: patrouilher (singular, for a member of the group), patrouilherez (feminine singular), patrouilherien (plural, name of the group). Please tell me if you take care of this or if not, where I should file the request.

gender for patroller usergroup has already been defined in https://gerrit.wikimedia.org/g/mediawiki/extensions/WikimediaMessages/+/1f70a761791d35c54c9695d9a0a01bf91f9f1201/i18n/wikimedia/br.json#83

	"group-patroller": "Patrouilherien",
	"group-patroller-member": "{{GENDER:$1|patrouilher|patrouilherez}}",
	"grouppage-patroller": "{{ns:project}}:Patrouilherien",
