About Maria Oles
I can't determine who Maria's mother was other than Jeanette O'Leary married to David Bennett. Maria was married to George Oles. She was born in Ireland, George in Canada. They lived in Sanilac County, Lexington, MI. Maria's headstone reads Maria Oles O'Leary apparently because that is what is showing on Find a Grave. This leads me to think Jeanette and David were not married when they had Maria.
Another confusing thing is that their daughter, Delia, born on 12/24/1874 is showing parents as Jno Oles and Martha Brown in her marriage record when she married Ernest Girardin, son of Emilie Dubois and Joseph Girardin. Why would she list her parents as John Oles and Martha Brown? I'm really confused.
