Geneology for
Courchaines of NE Wisconsin
Oconto & Manitowoc Counties

Last Revision 1/20/07


As best as I can determine, it appears that three Courchaine brothers(Peter, Joseph, & John) and one sister(Sophia) emigrated to Wisconsin during the years 1845 through 1857 from St. Francois-du-Lac, Quebec, Canada. A fourth Courchaine, Henry, also emigrated during this time and from the same place. He has different parents. Peter and Joseph then moved with their families to Oconto County during the late 1870s or early 1880s. Henry & John and their families remained in Manitowoc County. See this page on the Oconto Genweb site about the migration of the French families from Manitowoc to Oconto town of Lena. (click here)

I have listed each of the above families as generation 1. Their children will be listed under generation 2. Many pieces of information are missing. I have only focused my research on those individuals with the Courchaine surname for these two generations. Other Courchaine names can be found throughout this area and time period. Especially Courchaines of Menomonee Indian decent. How they are connected to these families is still not known.

The initial information was obtained by viewing actual records at the Oconto & Manitowoc County court houses during the early 1990s. Much more information is now available on-line that I am just beginning to go through. Many thanks have to go to all the individuals that are working so hard putting this information on-line.

My information is referenced as follows:

Dates followed by [cert] indicate that I found a certificate for that event, either birth, death, or marriage.

Comments from the certificate are placed in ( …) parenthesis following the [cert]

Other information obtained from documents or on-line are followed with:

Camille’s information along with my g-g-grandfathers(Peter) obituary links the three Courchaine brothers that emigrated from St. Francois - du Lac Canada.

The sister, Sophia Courchaine, married a Louis Greenwood Boisvert. I have exchanged information with a descendent of Sophia. Her name is Roxanne Mikkelson and she can be reached at

A David(Chalk) Courchaine from Washington State has a significant amount of information on the Courchaine’s of Canada. This information traces the Courchaines back to the 1600’s when they first emigrated from France to Canada. He can be reached at

Information in the brackets { .. } was obtained from conversations with various individuals. See the end of each family page for names & addresses

I have copies of selective records from the Diocese of Green Bay. They are all in French and have not been translated.

Misc. notes

The following data is on the Manitowoc GenWeb site and can not be definitively associated with any of the individual families in generation 1. Some spellings are close but not exact. They may even be un-related. Viewing the actual records may help in placing them somewhere.
