I have heard many stories over the years about how people said they were married- but no license could ever be found. Back in 1947 there was a terrible stigma over people living together, and many people just never got around to making it legal, but they told people they were married. Or it could be a common law marriage, or maybe one of the parties was married and never divorced. Divorces were hard to get and expensive, and sometimes people just didn't bother. It happened far more than people want to think, there were lots of marriages and divorces during the WWII and post-war years.
