“…while cleaning up the construction mess, out of the corner of my eye there lied a small blue envelope that had most [likely] been dropped into the wall as the house was being built almost 100 years prior! It was a letter sent from a sister in Bantry, Ireland, to a man named Con Shea here in Casper, Wyoming.”

“It was a letter thanking Mr. Shea for a present he had sent to his family back home in Ireland,” Smith told the Daily Mail. “There was also some catching up and keeping him abreast of the goings on back there in Ireland.”

Smith did some research to learn more about the man who built the home, who “…had immigrated to the US, and had become a very successful sheep herder here in Wyoming,” Smith explained to the outlet.
