My Great Grandmother was Emma Vermett of Monroe Monroe County Michig

My great grandmother was Emma Vermett of Monroe, Monroe County, Michigan. She married Clement Louis Navarre of Monroe, Monroe Co., Michigan. I would like to know her date of death. Emma Vermett's father was Noah. Noah was married to an Eliza. I have not been able to find their marriage license. I checked the Monroe Co., Mich. court house and found nothing on them. I am looking for Eliza's maiden name. Thank you kindly. Cathy Melzak
