They had not dated long and did not know each other very well, but Clyde was about to take a job at a pharmacy in Waterloo, Iowa, and they decided to get married. Rather than bother with a church wedding, they eloped, traveling to Knoxville, in Marion County, where Justice of the Peace I. H. Garritson married them on September 29, 1905.

John Wayne is not from where his parents met.
It is well known he is from a certain town in Iowa. They take pride in that fact. There are signs in the State about it.
