I received a 1905 marriage license from the Cuyahoga Archives and it has on the groom's side "Consent of Father Filed Mar 1905. The groom, Frank R. McGurer was only 20, so I assume that you had to be 21 to not have parental consent. His bride, Carrie Rockafellow was 21 and didn't need a signed consent. They were married by a Justice of the Peace, so it wasn't a Catholic requirement. I called the archives for a copy of the consent signed by the father and she said they don't have them and didn't know where they would be kept. I am not sure that it would provide any more info other than a signature, but am curious as to where you would find the signed consent. Thanks,
