There were several marriages performed Rev. Charles W. Houser in the early 1940's. I looked through some of the marriage applications on the Allen Genealogy Society site. These applications show when the application was made and when the marriage was performed. I found several where the applications was made and the marriage performed on the same day.
My parents were married about the same time. While they were married by the minister from my father's church, they were married in the Chapel at the Fort Wayne YMCA. There is a long story on the "Why", the point being that it is possible that Rev Houser was a young minister also living in near the court house in Fort Wayne and was available to marry them.
