Mary Hines, a widow from Ireland, came to WI in 1850's with 2 children,Dennis and Bridget. Bridget married Patrick Lavelle in Hudson, WI in 1860. I only recently discovered she had family in WI. A search of 1860 St. Croix census proved futile. I have a clue they may have been in Prairie du Chein. Any help will be appreciated.
