I haven't filled in too much of Peter's family because I wasn't sure of the connection. I found some information from baptismal records from St. Michael's for John Aubert's family, Henry Aubert's family, and a couple of items for Andrew Aubert. I'm also tracking the Auberts in the Chicago City Directories - they're primarily on Larrabee, Orchard, Willow, and Dayton Streets from 1855 on.
It would be great to see any pictures you'd be willing to share with me. My email adress is email@example.com
