I don’t have an answer for you, but just wanted to give you the website for the townhall of Petit-Tenquin where you’ll find their mailing and email addresses. If you have exact dates of events, or even an approximate date, it’ll be worth trying to send your request.
Petit-Tenquin archives are not yet online; Gros-Tenquin is but for the years only from 1793 to 1830.http://www.archivesnumerisees57.com/mdr/index.php/docnumView...
Refer to this website from time to time as they progressively add archives:http://fr.geneawiki.com/index.php/Archives_en_ligne
