MICHAEL McCanna & Maria Burhart - Minnesota

Trying to track down the descendants of Michael McCanna and Maria Burhart.They were m. in 1840 in Quebec, Canada.Had at least 3 children there, then wound up in Olmstead County, Minnesota. Children:

James
David
Simon
Rebecca
Martha
Thomas
Charlotte
Mary
Susan

Suspect there are several more who were likely born in Canada as well.I am researching the Burhart side of the family and am happy to share what I know about Maria's family.
