There are numerous Trichel/Trichell descendants in the Natchitoches Parish area who descend from Henri/Henry Triche/Trichsl/Trichel [numerous spelling variations found in records] who shows up in the colonial records there about 1737. In marriage records found in Natchitoches for Henri Trichel, he states the name of his parents as Adam Trichel of Strasbourg and Jeanne Elizabeth of Bern.
This information was found in Elizabeth Shown Mills book, Catholic Church Records, 1729-1803, entry #352.
I believe that all Trichels in the Natchitoches area descend from this one Henry Trichel and his progeny.I have never come across any mention of his other siblings in the Natchitoches Parish area nor any mention of when/where his parents, Adam and Jeanne Elizabeth or his siblings may have lived or died.
Henri Trichel and his descendants also show up numerous times in Winston de Ville's publication of the calendar of Natchitoches Post records.
