I may be able to help you on your Pierrre Bourelle. I have a Pierre Bourelle who died in 1915 inKankakee County that married Aliza "Lucy" Bachant (her parents were Roselalie Betourne and Israel Bachant - Rosealie was the sister to my maternal great-great grandfather Moses Betourne. Lucy and and Pierre had 8 children. I believe the Pierre you are looking for is the father to the Pierre I'm researching.
Let me know what information you have since you posted your messages. I look forward to hearing from you. I believe we have a match. I live in Chicago and go to Kankakee alot as well as the national archives and Newberry Library.
