My grandparents’ met sometime between 1938 and 1939. Grandpa was a sales rep with Swift & Company which sold meat to grocery stores. His routes took him to various places, including Abbeville, South Carolina, where my grandmother lived.
By 1940, they were dating and grandpa sent grandma this note (hopefully with some flowers or chocolates):

to say nothing of a Valentine – Henry”
Grandpa joined the Army Air Corps that year and they continued dating long-distance. Grandma and Grandpa married 5 June 1941 in Abbeville, South Carolina.

Happy Valentine’s Day!
