I just went to: https://www.familysearch.org
and found Frank and Adeline's marriage certificate. Family Search doesn't charge a fee but in order to get documents you need to register. The marriage certificate has a lot of information that you will need. It is on a page with 3 other certificates. It is the bottom right document. There are also many census records that you can pull the documents to you computer. If you have a membership to ancestry.com you can view the documents and print them out. There's another service that provides documents, too but you have to have a membership to it, as well and I don't have that. Do the research there and that will give you a lot of leads to where you need to go to find your answers. Then save the documents to your computer as well as add them to ancestry.com and you can upload them there.
