I'm in search of those with the surname 'Nicolas' of French origin. I believe my great great grandfather was Felix Francois Nicolas. He was born in France around 1832 and, I believe, emigrated to Canada and then to the U.S. and ended up in Washington, Iowa. He died 20 May 1891 and is buried in Lakewood Cemetery, Minneapolis, MN. I'm basically "stuck" and don't seem to be able to get any further back in history. I also am looking for the maiden name of his wife, who was of Irish descent and named Joanna Francia. Any clues appreciated!!
