Great! And I've made a few more posts in this thread that I don't know if you've seen - just a heads up because I may have replied to myself and then you wouldn't get a notification.
You'll also have access to Ancestry.com at the Minnesota Historical Society library - and at most public libraries.
So many individuals and branches of your family tree are now woven into this thread that as you go forward with your research, you might want to start a new thread for a particular quest. For example, you ask for help finding that elusive 1900 census record for George Sylvester Callais.
Then whenever you start a new thread, try to give all the background info and post the relevant records and state the sources to help your helpers help you. Post a link to this thread so that future searches can look back here for any additional helpful clues.
I am pleased to hear that your mom found so much - yes those family trees on Ancestry.com have some great photos. The information does not seem consistent and facts are often stated without sources - but that's just my brief impression, I didn't study the trees really closely.
