I don't know if this will help, or only add to the confusion.
In a book called 'Down Memory Lane in St Edmund's Township' by Dora & Cora Wyonch. I found a reference to Baptist Belrose. The book stated that he was the first Belrose in Canada, He was born in Alsace Loraine, France in the early 1700's. He served in Napoleon's army as a drummer boy at the age of 16. He and his wife, who were French Heugenot's (Protestants), came to Canada to escape the religious persecution. They left Quebec for the same reason. The book stated that this was Jacob & Michael Belrose's father. However since I know thier father was Jean Baptiste, and he could not have been born in the "early 1700s" I beleive this may have been Jean's father.
I have also come across the Anglisized version of Jean's name, John Bateast Belrose born in 1793 Quebec. Wife: Nancy Ann Bonesteel. This page includes lots of interesting information. See McKane & Lyons Genealogy home Page, master index.
In case you're interested Jean's sons Michael & Jacob where two of the original family's in Tobermory, St. Edmunds Twp. Ontario. Therefore quiet a bit of their history is preserved in local history books and the St Edmunds museum (includes Jacob's original cabin.
Good luck and thanks for the information you all have provided.
