There is no record of any CARTER/MORNINGSTAR marriage in the Lucas County Marriage Index, 1912-1939. There was a Velma MORNINGSTAR listed but she didn't marry a CARTER.
Perhaps, they were married in Perrysburg, Wood, OH. Perrysburg is just across the Maumee River, about 2 miles from Maumee. Or they may have been married in Monroe, Monroe, MI or Angola, Steuben, IN, neither of which required a waiting period.
