Years ago, when I began my research I obtained a copy of the 1867 marriage license of my relative. I thought that was the entire record. Last month while at the Family History Library in Salt Lake, I decided to make a digital copy of that record from their microfilm.
Turns out the marriage record was not just the license. There was an affidavit signed by my ancestor applying for the marriage license.
Had I not gone back I might never have obtained it.
Do you have the entire thing?
