Hi! I descent from Pierre and Cécile. Living in Montreal, Quebec, Canada, i was able to go several times to the Archives Nationales du Québec in Montreal. There, i have accessed the microfilm of the parish of Lac-Des-Deux-Montagnes wich is L'Annonciation-de-la-Bienheureuse-Vierge-Marie-d'Oka.There, you see Dicaire, sometimes Diquerre and other few variations. There is even something more interesting to know about their parents. The father of Cécile Annenharisson is Julien. He is stated as english and the chief of praying at the mission, which Deux-Montagnes was at the time. The mission was under the responsibility of the Sulpicians. There is something new too on Jean-Louis Dicaire/Dicker. From a new book on the german immigrants in Canada and Quebec province, i read that the first german in Montreal his Jean Decker, born in 1694 in Newfoundland and baptised in Montreal in 1706. I had wrote about this on the forum of rootsweb for the Dicaire, seek the correspondance between Mr. Nicklen and me, you will learn something interesting. I have e-mailed the author of the book who replied that he was not a specialist of the early period. His name is Mr. Manuel Meune, a teacher in german studies at university. Mr. Nicklen and me are trying to receive an answer from the source wich was found in the bibliography of Mr Meune book. So far, we have got no response yet. It seems that even the archivist of Newfoundland Archives can't find any Hauzerburg or Hauzerbury on any old map that they have, but there is a Hauzerberg in Germany... Also, to add more confusion, several Dicaire/Dicker married with some Titly/Titley which are from Essen, Germany descent. We have put the president of the association of the francophones of german origin, Mr. Kaufholtz-Couture on the tracking of this first german settler in Montreal. I found a free nice web site with Dicaire/Dicker, you should check it. See www.metisduquebec.caGood Luck!
