Dear Michelle, In Denissen's book, on pg. 898, no.42, a Robert Navarre is listed, born 27 Mar 1842, married 22 Nov. 1870, Mary Angelica Duclos, Born Monroe, 14 May 1848, dau of Francis Duclos and Angelica Bourbonnay.Children listed, Charles, Born 19 Sept. 1871.
This might not be the family you are looking for, but a good place to start.Order the 1880 Census for Monroe and see if this family is listed with other children.denissen's book only lists children baptized in St. Mary's church, but the Census lists everybody inthe family.Also The Navarre News, Navarre Family Association, 2220 McGregor Blvd., #120, Fort Myers, Florida 33901, is a good source of info.I hope this helps and good luck. Write me back if you have any questions. Andre, firstname.lastname@example.org
