I recall the Nadings in Garnavillo, Iowa from the 1950s and 1960. Eldora or Doris Nading married my cousin Harvey Lee Borcherding and as far as I know they still live on Main Street In Garnavillo, Iowa. The area code there is 319. The Zip code is 52052 so you should be able to address a letter to Harvey Borcherding, Garnavillo, Iowa 52052. Garnavillo is a small town of 700 people on U.S. Highway 52 which is two lanes. Everyone there knows everyone else so you should have no problems mailing to Harvey.
